+.AP char *message in

+.AP char *element in
+String to record as one element of \fBerrorCode\fR variable.
+Last \fIelement\fR argument must be NULL.
+.BE
+
+.SH DESCRIPTION
+.PP
+These procedures are used to manipulate two global variables
+that hold information about errors.
+The variable \fBerrorInfo\fR holds a stack trace of the
+operations that were in progress when an error occurred, and
+is intended to be human-readable.
+The variable \fBerrorCode\fR holds a list of items that
+are intended to be machine-readable.
+The first item in \fBerrorCode\fR identifies the class of
+.VS
+error that occurred (e.g. POSIX means an error occurred in
+.VE
+a POSIX system call) and additional elements in \fBerrorCode\fR
+hold additional pieces of information that depend on the class.
+See the Tcl overview manual entry for details on the various
+formats for \fBerrorCode\fR.
+.PP
+The \fBerrorInfo\fR variable is gradually built up as an
+error unwinds through the nested operations.
+Each time an error code is returned to \fBTcl_Eval\fR
+it calls the procedure \fBTcl_AddErrorInfo\fR to add
+additional text to \fBerrorInfo\fR describing the
+command that was being executed when the error occurred.
+By the time the error has been passed all the way back
+to the application, it will contain a complete trace
+of the activity in progress when the error occurred.
+.PP
+It is sometimes useful to add additional information to
+\fBerrorInfo\fR beyond what can be supplied automatically
+by \fBTcl_Eval\fR.
+\fBTcl_AddErrorInfo\fR may be used for this purpose:
+its \fImessage\fR argument contains an additional
+string to be appended to \fBerrorInfo\fR.
+For example, the \fBsource\fR command calls \fBTcl_AddErrorInfo\fR
+to record the name of the file being processed and the
+line number on which the error occurred;  for Tcl procedures, the
+procedure name and line number within the procedure are recorded,
+and so on.
+The best time to call \fBTcl_AddErrorInfo\fR is just after
+\fBTcl_Eval\fR has returned \fBTCL_ERROR\fR.
+In calling \fBTcl_AddErrorInfo\fR, you may find it useful to
+use the \fBerrorLine\fR field of the interpreter (see the
+\fBTcl_Interp\fR manual entry for details).
+.PP
+The procedure \fBTcl_SetErrorCode\fR is used to set the
+\fBerrorCode\fR variable.
+Its \fIelement\fR arguments give one or more strings to record
+in \fBerrorCode\fR:  each \fIelement\fR will become one item
+of a properly-formed Tcl list stored in \fBerrorCode\fR.
+\fBTcl_SetErrorCode\fR is typically invoked just before returning
+an error.
+If an error is returned without calling \fBTcl_SetErrorCode\fR
+then the Tcl interpreter automatically sets \fBerrorCode\fR
+to \fBNONE\fR.
+.PP
+\fBTcl_PosixError\fR
+.VS
+sets the \fBerrorCode\fR variable after an error in a POSIX kernel call.
+It reads the value of the \fBerrno\fR C variable and calls
+\fBTcl_SetErrorCode\fR to set \fBerrorCode\fR in the
+\fBPOSIX\fR format.
+In addition, \fBTcl_PosixError\fR returns a human-readable
+.VE
+diagnostic message for the error (this is the same value that
+will appear as the third element in \fBerrorCode\fR).
+It may be convenient to include this string as part of the
+error message returned to the application in \fIinterp->result\fR.
+.PP
+It is important to call the procedures described here rather than
+setting \fBerrorInfo\fR or \fBerrorCode\fR directly with
+\fBTcl_SetVar\fR.
+The reason for this is that the Tcl interpreter keeps information
+about whether these procedures have been called.
+For example, the first time \fBTcl_AppendResult\fR is called
+for an error, it clears the existing value of \fBerrorInfo\fR
+and adds the error message in \fIinterp->result\fR to the variable
+before appending \fImessage\fR;  in subsequent calls, it just
+appends the new \fImessage\fR.
+When \fBTcl_SetErrorCode\fR is called, it sets a flag indicating
+that \fBerrorCode\fR has been set;  this allows the Tcl interpreter
+to set \fBerrorCode\fR to \fBNONE\fB if it receives an error return
+when \fBTcl_SetErrorCode\fR hasn't been called.
+.PP
+If the procedure \fBTcl_ResetResult\fR is called, it clears all
+of the state associated with \fBerrorInfo\fR and \fBerrorCode\fR
+(but it doesn't actually modify the variables).
+If an error had occurred, this will clear the error state to
+make it appear as if no error had occurred after all.

+.SH DESCRIPTION
+.PP
+\fBTcl_AppInit\fR is a procedure that is invoked by the main programs
+for Tcl applications such as \fBtclsh\fR and \fBwish\fR.
+Its purpose is to allow new Tcl applications to be created without
+modifying existing main programs such as those for \fBtclsh\fR
+and \fBwish\fR.
+To create a new application simply write a new version of
+\fBTcl_AppInit\fR to replace the default version provided by Tcl,
+then link your new \fBTcl_AppInit\fR with the Tcl library, which
+contains the main program from \fBtclsh\fR (be sure to specify the
+switch ``\fB\-u _main\fR'' to the linker to force it to use the
+version of \fBmain\fR from the Tcl library).
+.PP
+\fBTcl_AppInit\fR is invoked after other initialization in
+\fBmain\fR and before entering the main loop to process commands.
+Here are some examples of things that \fBTcl_AppInit\fR might do:
+.IP [1]
+Call initialization procedures for various packages used by
+the application.
+Each initialization procedure adds new commands to \fIinterp\fR
+for its package and performs other package-specific initialization.
+.IP [2]
+Process command-line arguments, which can be accessed from the
+Tcl variables \fBargv\fR and \fBargv0\fR in \fIinterp\fR.
+.IP [3]
+Invoke a startup script to initialize the application.

+.BE
+
+.SH DESCRIPTION
+.PP
+These procedures provide a safe mechanism for dealing with
+asynchronous events such as signals.
+If an event such as a signal occurs while a Tcl script is being
+evaluated then it isn't safe to take any substantive action to
+process the event.
+For example, it isn't safe to evaluate a Tcl script since the
+intepreter may already be in the middle of evaluating a script;
+it may not even be safe to allocate memory, since a memory
+allocation could have been in progress when the event occurred.
+The only safe approach is to set a flag indicating that the event
+occurred, then handle the event later when the world has returned
+to a clean state, such as after the current Tcl command completes.
+.PP
+\fBTcl_AsyncCreate\fR creates an asynchronous handler and returns
+a token for it.
+The asynchronous handler must be created before
+any occurrences of the asynchronous event that it is intended
+to handle (it is not safe to create a handler at the time of
+an event).
+When an asynchronous event occurs the code that detects the event
+(such as a signal handler) should call \fBTcl_AsyncMark\fR with the
+token for the handler.
+\fBTcl_AsyncMark\fR will mark the handler as ready to execute, but it
+will not invoke the handler immediately.
+Tcl will call the \fIproc\fR associated with the handler later, when
+the world is in a safe state, and \fIproc\fR can then carry out
+the actions associated with the asynchronous event.
+\fIProc\fR should have arguments and result that match the
+type \fBTcl_AsyncProc\fR:
+.nf
+.RS
+typedef int Tcl_AsyncProc(
+.RS
+ClientData \fIclientData\fR,
+Tcl_Interp *\fIinterp\fR,
+int \fIcode\fR);
+.RE
+.RE
+.fi
+The \fIclientData\fR will be the same as the \fIclientData\fR
+argument passed to \fBTcl_AsyncCreate\fR when the handler was
+created.
+If \fIproc\fR is invoked just after a command has completed
+execution in an interpreter, then \fIinterp\fR will identify
+the interpreter in which the command was evaluated and
+\fIcode\fR will be the completion code returned by that
+command.
+The command's result will be present in \fIinterp->result\fR.
+When \fIproc\fR returns, whatever it leaves in \fIinterp->result\fR
+will be returned as the result of the command and the integer
+value returned by \fIproc\fR will be used as the new completion
+code for the command.
+.PP
+It is also possible for \fIproc\fR to be invoked when no interpreter
+is active.
+This can happen, for example, if an asynchronous event occurs while
+the application is waiting for interactive input or an X event.
+In this case \fIinterp\fR will be NULL and \fIcode\fR will be
+0, and the return value from \fIproc\fR will be ignored.
+.PP
+The procedure \fBTcl_AsyncInvoke\fR is called to invoke all of the
+handlers that are ready.
+The global variable \fBtcl_AsyncReady\fR will be non-zero whenever any
+asynchronous handlers are ready;  it can be checked to avoid calls
+to \fBTcl_AsyncInvoke\fR when there are no ready handlers.
+Tcl checks \fBtcl_AsyncReady\fR after each command is evaluated
+and calls \fBTcl_AsyncInvoke\fR if needed.
+Applications may also call \fBTcl_AsyncInvoke\fR at interesting
+times for that application.
+For example, Tk's event handler checks \fBtcl_AsyncReady\fR
+after each event and calls \fBTcl_AsyncInvoke\fR if needed.
+The \fIinterp\fR and \fIcode\fR arguments to \fBTcl_AsyncInvoke\fR
+have the same meaning as for \fIproc\fR:  they identify the active
+intepreter, if any, and the completion code from the command
+that just completed.
+.PP
+\fBTcl_AsyncDelete\fR removes an asynchronous handler so that
+its \fIproc\fR will never be invoked again.
+A handler can be deleted even when ready, and it will still
+not be invoked.
+.PP
+If multiple handlers become active at the same time, the
+handlers are invoked in the order they were created (oldest
+handler first).
+The \fIcode\fR and \fIinterp->result\fR for later handlers
+reflect the values returned by earlier handlers, so that
+the most recently created handler has last say about
+the interpreter's result and completion code.
+If new handlers become ready while handlers are executing,
+\fBTcl_AsyncInvoke\fR will invoke them all;  at each point it
+invokes the highest-priority (oldest) ready handler, repeating
+this over and over until there are no longer any ready handlers.
+
+.SH WARNING
+.PP
+It is almost always a bad idea for an asynchronous event
+handler to modify \fIinterp->result\fR or return a code different
+from its \fIcode\fR argument.
+This sort of behavior can disrupt the execution of scripts in
+subtle ways and result in bugs that are extremely difficult
+to track down.
+If an asynchronous event handler needs to evaluate Tcl scripts
+then it should first save \fIinterp->result\fR plus the values
+of the variables \fBerrorInfo\fR and \fBerrorCode\fR (this can
+be done, for example, by storing them in dynamic strings).
+When the asynchronous handler is finished it should restore
+\fIinterp->result\fR, \fBerrorInfo\fR, and \fBerrorCode\fR,
+and return the \fIcode\fR argument.

+.BE
+
+.SH DESCRIPTION
+.PP
+\fBTcl_Concat\fR is a utility procedure used by several of the
+Tcl commands.  Given a collection of strings, it concatenates
+them together into a single string, with the original strings
+separated by spaces.  This procedure behaves differently than
+\fBTcl_Merge\fR, in that the arguments are simply concatenated:
+no effort is made to ensure proper list structure.
+However, in most common usage the arguments will all be proper
+lists themselves;  if this is true, then the result will also have
+proper list structure.
+.PP
+\fBTcl_Concat\fR eliminates leading and trailing white space as it
+copies strings from \fBargv\fR to the result.  If an element of
+\fBargv\fR consists of nothing but white space, then that string
+is ignored entirely.  This white-space removal was added to make
+the output of the \fBconcat\fR command cleaner-looking.
+.PP
+The result string is dynamically allocated
+using \fBmalloc()\fR;  the caller must eventually release the space
+by calling \fBfree()\fR.

+.SH DESCRIPTION
+.PP
+\fBTcl_CreateCommand\fR defines a new command in \fIinterp\fR and associates
+it with procedure \fIproc\fR such that whenever \fIcmdName\fR is
+invoked as a Tcl command (via a call to \fBTcl_Eval\fR) the Tcl interpreter
+will call \fIproc\fR
+to process the command.  If there is already a command \fIcmdName\fR
+associated with the interpreter, it is deleted.  \fIProc\fP should
+have arguments and result that match the type \fBTcl_CmdProc\fR:
+.nf
+.RS
+typedef int Tcl_CmdProc(
+.RS
+ClientData \fIclientData\fR,
+Tcl_Interp *\fIinterp\fR,
+int \fIargc\fR,
+char *\fIargv\fR[]);
+.RE
+.RE
+.fi
+When \fIproc\fR is invoked the \fIclientData\fP and \fIinterp\fR
+parameters will be copies of the \fIclientData\fP and \fIinterp\fR
+arguments given to \fBTcl_CreateCommand\fR.
+Typically, \fIclientData\fR points to an application-specific
+data structure that describes what to do when the command procedure
+is invoked.  \fIArgc\fR and \fIargv\fR describe the arguments to
+the command, \fIargc\fR giving the number of arguments (including
+the command name) and \fIargv\fR giving the values of the arguments
+as strings.  The \fIargv\fR array will contain \fIargc\fR+1 values;
+the first \fIargc\fR values point to the argument strings, and the
+last value is NULL.
+.PP
+\fIProc\fR must return an integer code that is either \fBTCL_OK\fR, \fBTCL_ERROR\fR,
+\fBTCL_RETURN\fR, \fBTCL_BREAK\fR, or \fBTCL_CONTINUE\fR.  See the Tcl overview man page
+for details on what these codes mean.  Most normal commands will only
+return \fBTCL_OK\fR or \fBTCL_ERROR\fR.  In addition, \fIproc\fR must set
+\fIinterp->result\fR to point to a string value;
+in the case of a \fBTCL_OK\fR return code this gives the result
+of the command, and in the case of \fBTCL_ERROR\fR it gives an error message.
+The \fBTcl_SetResult\fR procedure provides an easy interface for setting
+the return value;  for complete details on how the \fIinterp->result\fR
+field is managed, see the \fBTcl_Interp\fR man page.
+Before invoking a command procedure,
+\fBTcl_Eval\fR sets \fIinterp->result\fR to point to an empty string, so simple
+commands can return an empty result by doing nothing at all.
+.PP
+.VS
+The contents of the \fIargv\fR array belong to Tcl and are not
+guaranteed to persist once \fIproc\fR returns:  \fIproc\fR should
+not modify them, nor should it set \fIinterp->result\fR to point
+anywhere within the \fIargv\fR values.
+Call \fBTcl_SetResult\fR with status \fBTCL_VOLATILE\fR if you want
+to return something from the \fIargv\fR array.
+.VE
+.PP
+\fIDeleteProc\fR will be invoked when (if) \fIcmdName\fR is deleted.
+This can occur through a call to \fBTcl_DeleteCommand\fR or \fBTcl_DeleteInterp\fR,
+or by replacing \fIcmdName\fR in another call to \fBTcl_CreateCommand\fR.
+\fIDeleteProc\fR is invoked before the command is deleted, and gives the
+application an opportunity to release any structures associated
+with the command.  \fIDeleteProc\fR should have arguments and
+result that match the type \fBTcl_CmdDeleteProc\fR:
+.nf
+.RS
+.sp
+typedef void Tcl_CmdDeleteProc(ClientData \fIclientData\fR);
+.sp
+.RE
+.fi
+The \fIclientData\fR argument will be the same as the \fIclientData\fR
+argument passed to \fBTcl_CreateCommand\fR.
+.PP
+\fBTcl_DeleteCommand\fR deletes a command from a command interpreter.
+Once the call completes, attempts to invoke \fIcmdName\fR in
+\fIinterp\fR will result in errors.
+If \fIcmdName\fR isn't bound as a command in \fIinterp\fR then
+\fBTcl_DeleteCommand\fR does nothing and returns -1;  otherwise
+it returns 0.
+There are no restrictions on \fIcmdName\fR:  it may refer to
+a built-in command, an application-specific command, or a Tcl procedure.
+.PP
+.VS
+\fBTcl_GetCommandInfo\fR checks to see whether its \fIcmdName\fR argument
+exists as a command in \fIinterp\fR.  If not then it returns 0.
+Otherwise it places information about the command in the structure
+pointed to by \fIinfoPtr\fR and returns 1.
+Tcl_CmdInfo structures have fields named \fIproc\fR, \fIclientData\fR,
+and \fIdeleteProc\fR, which have the same meaning as the corresponding
+arguments to \fBTcl_CreateCommand\fR.
+There is also a field \fIdeleteData\fR, which is the ClientData value
+to pass to \fIdeleteProc\fR;  it is normally the same as
+\fIclientData\fR but may be set independently using the
+\fBTcl_SetCommandInfo\fR procedure.
+.PP
+\fBTcl_SetCommandInfo\fR is used to modify the procedures and
+ClientData values associated with a command.
+Its \fIcmdName\fR argument is the name of a command in \fIinterp\fR.
+If this command exists then \fBTcl_SetCommandInfo\fR returns 0.
+Otherwise, it copies the information from \fI*infoPtr\fR to
+Tcl's internal structure for the command and returns 1.
+Note that this procedure allows the ClientData for a command's
+deletion procedure to be given a different value than the ClientData
+for its command procedure.

+
+.SH DESCRIPTION
+.PP
+Tcl allows a number of mathematical functions to be used in
+expressions, such as \fBsin\fR, \fBcos\fR, and \fBhypot\fR.
+\fBTcl_CreateMathFunc\fR allows applications to add additional functions
+to those already provided by Tcl or to replace existing functions.
+\fIName\fR is the name of the function as it will appear in expressions.
+If \fIname\fR doesn't already exist as a function then a new function
+is created.  If it does exist, then the existing function is replaced.
+\fINumArgs\fR and \fIargTypes\fR describe the arguments to the function.
+Each entry in the \fIargTypes\fR array must be either TCL_INT, TCL_DOUBLE,
+or TCL_EITHER to indicate whether the corresponding argument must be an
+integer, a double-precision floating value, or either, respectively.
+.PP
+Whenever the function is invoked in an expression Tcl will invoke
+\fIproc\fR.  \fIProc\fR should have arguments and result that match
+the type \fBTcl_MathProc\fR:
+.nf
+.RS
+typedef int Tcl_MathProc(
+.RS
+ClientData \fIclientData\fR,
+Tcl_Interp *\fIinterp\fR,
+Tcl_Value *\fIargs\fR,
+Tcl_Value *resultPtr\fR);
+.RE
+.RE
+.fi
+.PP
+When \fIproc\fR is invoked the \fIclientData\fR and \fIinterp\fR
+arguments will be the same as those passed to \fBTcl_CreateMathFunc\fR.
+\fIArgs\fR will point to an array of \fInumArgs\fR Tcl_Value structures,
+which describe the actual arguments to the function:
+.nf
+.RS
+typedef struct Tcl_Value {
+.RS
+Tcl_ValueType \fItype\fR;
+int \fIintValue\fR;
+double \fIdoubleValue\fR;
+.RE
+} Tcl_Value;
+.RE
+.fi
+.PP
+The \fItype\fR field indicates the type of the argument and is
+either TCL_INT or TCL_DOUBLE.
+It will match the \fIargTypes\fR value specified for the function unless
+the \fIargTypes\fR value was TCL_EITHER. Tcl converts
+the argument supplied in the expression to the type requested in
+\fIargTypes\fR, if that is necessary.
+Depending on the value of the \fItype\fR field, the \fIintValue\fR
+or \fIdoubleValue\fR field will contain the actual value of the argument.
+.PP
+\fIProc\fR should compute its result and store it either as an integer
+in \fIresultPtr->intValue\fR or as a floating value in
+\fIresultPtr->doubleValue\fR.
+It should set also \fIresultPtr->type\fR to either TCL_INT or TCL_DOUBLE
+to indicate which value was set.
+Under normal circumstances \fIproc\fR should return TCL_OK.
+If an error occurs while executing the function, \fIproc\fR should
+return TCL_ERROR and leave an error message in \fIinterp->result\fR.

+.BE
+
+.SH DESCRIPTION
+.PP
+\fBTcl_CreatePipeline\fR processes the \fIargv\fR array and sets
+up one or more child processes in a pipeline configuration.
+\fBTcl_CreatePipeline\fR handles pipes specified with ``|'',
+input redirection specified with ``<'' or ``<<'', and output
+redirection specified with ``>'';  see the documentation for
+the \fBexec\fR command for details on these specifications.
+The return value from \fBTcl_CreatePipeline\fR is a count of
+the number of child processes created;  the process identifiers
+for those processes are stored in a \fImalloc\fR-ed array and
+a pointer to that array is stored at \fI*pidArrayPtr\fR.
+It is the caller's responsibility to free the array when finished
+with it.
+.PP
+If the \fIinPipePtr\fR, \fIoutPipePtr\fR, and \fIerrFilePtr\fR
+arguments are NULL then the pipeline's standard input, standard
+output, and standard error are taken from the corresponding
+streams of the process.  Non-NULL values may be specified for
+these arguments to use pipes for standard input and standard
+output and a file for standard error.  \fBTcl_CreatePipeline\fR
+will create the requested pipes or file and return file identifiers
+that may be used to read or write them.  It is the caller's
+responsibility to close all of these files when they are no
+longer needed.  If \fIargv\fR specifies redirection for standard
+input or standard output, then pipes will not be created even
+if requested by the \fIinPipePtr\fR and \fIoutPipePtr\fR
+arguments.
+.PP
+If an error occurs in \fBTcl_CreatePipeline\fR (e.g. ``|'' or
+``<'' was the last argument in \fIargv\fR, or it wasn't possible
+to fork off a child), then -1 is returned
+and \fIinterp->result\fR is set to an error message.

+.AP Tcl_Interp *interp in
+Interpreter containing command to be traced or untraced.
+.AP int level in
+Only commands at or below this nesting level will be traced.  1 means

+.BE
+
+.SH DESCRIPTION
+.PP
+\fBTcl_CreateTrace\fR arranges for command tracing.  From now on, \fIproc\fR
+will be invoked before Tcl calls command procedures to process
+commands in \fIinterp\fR.  The return value from
+\fBTcl_CreateTrace\fR is a token for the trace,
+which may be passed to \fBTcl_DeleteTrace\fR to remove the trace.  There may
+be many traces in effect simultaneously for the same command interpreter.
+.PP
+\fIProc\fR should have arguments and result that match the
+type \fBTcl_CmdTraceProc\fR:
+.nf
+.sp
+.RS
+typedef void Tcl_CmdTraceProc(
+.RS
+ClientData \fIclientData\fR,
+Tcl_Interp *\fIinterp\fR,
+int \fIlevel\fR,
+char *\fIcommand\fR,
+Tcl_CmdProc *\fIcmdProc\fR,
+ClientData \fIcmdClientData\fR,
+int \fIargc\fR,
+char *\fIargv\fR[]));
+.sp
+.RE
+.RE
+.fi
+The \fIclientData\fP and \fIinterp\fP parameters are
+copies of the corresponding arguments given to \fBTcl_CreateTrace\fR.
+\fIClientData\fR typically points to an application-specific
+data structure that describes what to do when \fIproc\fR
+is invoked.  \fILevel\fR gives the nesting level of the command
+(1 for top-level commands passed to \fBTcl_Eval\fR by the application,
+2 for the next-level commands passed to \fBTcl_Eval\fR as part of parsing
+or interpreting level-1 commands, and so on).  \fICommand\fR
+points to a string containing the text of the
+command, before any argument substitution.
+\fICmdProc\fR contains the address of the command procedure that
+will be called to process the command (i.e. the \fIproc\fR argument
+of some previous call to \fBTcl_CreateCommand\fR) and \fIcmdClientData\fR
+contains the associated client data for \fIcmdProc\fR (the \fIclientData\fR
+value passed to \fBTcl_CreateCommand\fR).  \fIArgc\fR and \fIargv\fR give
+the final argument information that will be passed to \fIcmdProc\fR, after
+command, variable, and backslash substitution.
+\fIProc\fR must not modify the \fIcommand\fR or \fIargv\fR strings.
+.PP
+Tracing will only occur for commands at nesting level less than
+or equal to the \fIlevel\fR parameter (i.e. the \fIlevel\fR
+parameter to \fIproc\fR will always be less than or equal to the
+\fIlevel\fR parameter to \fBTcl_CreateTrace\fR).
+.PP
+Calls to \fIproc\fR will be made by the Tcl parser immediately before
+it calls the command procedure for the command (\fIcmdProc\fR).  This
+occurs after argument parsing and substitution, so tracing for
+substituted commands occurs before tracing of the commands
+containing the substitutions.  If there is a syntax error in a
+command, or if there is no command procedure associated with a
+command name, then no tracing will occur for that command.  If a
+string passed to Tcl_Eval contains multiple commands (bracketed, or
+on different lines) then multiple calls to \fIproc\fR will occur,
+one for each command.  The \fIcommand\fR string for each of these
+trace calls will reflect only a single command, not the entire string
+passed to Tcl_Eval.
+.PP
+\fBTcl_DeleteTrace\fR removes a trace, so that no future calls will be
+made to the procedure associated with the trace.  After \fBTcl_DeleteTrace\fR
+returns, the caller should never again use the \fItrace\fR token.

+.BE
+
+.SH DESCRIPTION
+.PP
+Dynamic strings provide a mechanism for building up arbitrarily long
+strings by gradually appending information.  If the dynamic string is
+short then there will be no memory allocation overhead;  as the string
+gets larger, additional space will be allocated as needed.
+.PP
+\fBTcl_DStringInit\fR initializes a dynamic string to zero length.
+The Tcl_DString structure must have been allocated by the caller.
+No assumptions are made about the current state of the structure;
+anything already in it is discarded.
+If the structure has been used previously, \fBTcl_DStringFree\fR should
+be called first to free up any memory allocated for the old
+string.
+.PP
+\fBTcl_DStringAppend\fR adds new information to a dynamic string,
+allocating more memory for the string if needed.
+If \fIlength\fR is less than zero then everything in \fIstring\fR
+is appended to the dynamic string;  otherwise \fIlength\fR
+specifies the number of bytes to append.
+\fBTcl_DStringAppend\fR returns a pointer to the characters of
+the new string.  The string can also be retrieved from the
+\fIstring\fR field of the Tcl_DString structure.
+.PP
+\fBTcl_DStringAppendElement\fR is similar to \fBTcl_DStringAppend\fR
+except that it doesn't take a \fIlength\fR argument (it appends
+all of \fIstring\fR) and it converts the string to a proper list element
+before appending.
+\fBTcl_DStringAppendElement\fR adds a separator space before the
+new list element unless the new list element is the first in a
+list or sub-list (i.e. either the current string is empty, or it
+contains the single character ``{'', or the last two characters of
+the current string are `` {'').
+\fBTcl_DStringAppendElement\fR returns a pointer to the
+characters of the new string.
+.PP
+\fBTcl_DStringStartSublist\fR and \fBTcl_DStringEndSublist\fR can be
+used to create nested lists.
+To append a list element that is itself a sublist, first
+call \fBTcl_DStringStartSublist\fR, then call \fBTcl_DStringAppendElement\fR
+for each of the elements in the sublist, then call
+\fBTcl_DStringEndSublist\fR to end the sublist.
+\fBTcl_DStringStartSublist\fR appends a space character if needed,
+followed by an open brace;  \fBTcl_DStringAppendElement\fR appends
+a close brace.
+Lists can be nested to any depth.
+.PP
+\fBTcl_DStringLength\fR is a macro that returns the current length
+of a dynamic string (not including the terminating null character).
+\fBTcl_DStringValue\fR is a  macro that returns a pointer to the
+current contents of a dynamic string.
+.PP
+\fBTcl_DStringTrunc\fR truncates a dynamic string to a given length.
+It has no effect if the string was already smaller than \fInewLength\fR.
+This procedure does not free up the string's storage space, even
+if the string is truncated to zero length, so \fBTcl_DStringFree\fR
+will still need to be called.
+.PP
+\fBTcl_DStringFree\fR should be called when you're finished using
+the string.  It frees up any memory that was allocated for the string
+and reinitializes the string's value to an empty string.
+.PP
+\fBTcl_DStringResult\fR sets the result of \fIinterp\fR to the value of
+the dynamic string given by \fIdsPtr\fR.  It does this by moving
+a pointer from \fIdsPtr\fR to \fIinterp->result\fR.
+This saves the cost of allocating new memory and copying the string.
+\fBTcl_DStringResult\fR also reinitializes the dynamic string to
+an empty string.

+
+.SH DESCRIPTION
+.PP
+.VS
+\fBTcl_DetachPids\fR and \fBTcl_ReapDetachedProcs\fR provide a
+mechanism for managing subprocesses that are running in background.
+These procedures are needed because the parent of a process must
+eventually invoke the \fBwaitpid\fR kernel call (or one of a few other
+similar kernel calls) to wait for the child to exit.  Until the
+parent waits for the child, the child's state cannot be completely
+reclaimed by the system.  If a parent continually creates children
+and doesn't wait on them, the system's process table will eventually
+overflow, even if all the children have exited.
+.PP
+\fBTcl_DetachPids\fR may be called to ask Tcl to take responsibility
+for one or more processes whose process ids are contained in the
+\fIpidPtr\fR array passed as argument.  The caller presumably
+has started these processes running in background and doesn't
+want to have to deal with them again.
+.PP
+\fBTcl_ReapDetachedProcs\fR invokes the \fBwaitpid\fR kernel call
+on each of the background processes so that its state can be cleaned
+up if it has exited.  If the process hasn't exited yet,
+\fBTcl_ReapDetachedProcs\fR doesn't wait for it to exit;  it will check again
+the next time it is invoked.
+Tcl automatically calls \fBTcl_ReapDetachedProcs\fR each time the
+\fBexec\fR command is executed, so in most cases it isn't necessary
+for any code outside of Tcl to invoke \fBTcl_ReapDetachedProcs\fR.
+However, if you call \fBTcl_DetachPids\fR in situations where the
+\fBexec\fR command may never get executed, you may wish to call
+\fBTcl_ReapDetachedProcs\fR from time to time so that background
+processes can be cleaned up.

+These procedures provide access to Tcl's file naming mechanism.
+\fBTcl_EnterFile\fR enters an open file into Tcl's file table so
+that it can be accessed using Tcl commands like \fBgets\fR,
+\fBputs\fR, \fBseek\fR, and \fBclose\fR.
+It returns in \fIinterp->result\fR an identifier such as \fBfile4\fR
+that can be used to refer to the file in subsequent Tcl commands.
+\fBTcl_EnterFile\fR is typically used to implement new Tcl commands
+that open sockets, pipes, or other kinds of files not already supported
+by the built-in commands.
+.PP
+\fBTcl_GetOpenFile\fR takes as argument a file identifier of the form
+returned by the \fBopen\fR command or \fBTcl_EnterFile\fR and
+returns at \fI*filePtr\fR a pointer to the FILE structure for
+the file.
+The \fIwrite\fR argument indicates whether the FILE pointer will
+be used for reading or writing.
+In some cases, such as a file that connects to a pipeline of
+subprocesses, different FILE pointers will be returned for reading
+and writing.
+\fBTcl_GetOpenFile\fR normally returns TCL_OK.
+If an error occurs in \fBTcl_GetOpenFile\fR (e.g. \fIstring\fR didn't
+make any sense or \fIcheckUsage\fR was set and the file wasn't opened
+for the access specified by \fIwrite\fR) then TCL_ERROR is returned
+and \fIinterp->result\fR will contain an error message.
+If \fIcheckUsage\fR is zero and the file wasn't opened for the
+access specified by \fIwrite\fR, then the FILE pointer returned
+at \fI*filePtr\fR may not correspond to \fIwrite\fR.
+.PP
+\fBTcl_FilePermissions\fR returns an OR-ed combination of the
+mask bits TCL_FILE_READABLE and TCL_FILE_WRITABLE; these indicate
+whether the given file was opened for reading or writing or both.
+If \fIfile\fR does not refer to a file in Tcl's file table then

+
+.SH DESCRIPTION
+.PP
+All four of these procedures execute Tcl commands.
+\fBTcl_Eval\fR is the core procedure:  it parses commands
+from \fIcmd\fR and executes them in
+.VS
+order until either an error occurs or it reaches the end of the string.
+.VE
+The return value from \fBTcl_Eval\fR is one
+of the Tcl return codes \fBTCL_OK\fR, \fBTCL_ERROR\fR, \fBTCL_RETURN\fR, \fBTCL_BREAK\fR, or
+\fBTCL_CONTINUE\fR, and \fIinterp->result\fR will point to
+a string with additional information (result value or error message).
+This return information corresponds to the last command executed from
+\fIcmd\fR.
+.PP
+\fBTcl_VarEval\fR takes any number of string arguments
+of any length, concatenates
+them into a single string, then calls \fBTcl_Eval\fR to
+execute that string as a Tcl command.
+It returns the result of the command and also modifies
+\fIinterp->result\fR in the usual fashion for Tcl commands.  The
+last argument to \fBTcl_VarEval\fR must be NULL to indicate the end
+of arguments.
+.PP
+\fBTcl_EvalFile\fR reads the file given by \fIfileName\fR and evaluates
+its contents as a Tcl command by calling \fBTcl_Eval\fR.  It returns
+a standard Tcl result that reflects the result of evaluating the
+file.
+If the file couldn't be read then a Tcl error is returned to describe
+why the file couldn't be read.
+.PP
+\fBTcl_GlobalEval\fR is similar to \fBTcl_Eval\fR except that it
+processes the command at global level.
+This means that the variable context for the command consists of
+global variables only (it ignores any Tcl procedure that is active).
+This produces an effect similar to the Tcl command ``\fBuplevel 0\fR''.
+.PP
+During the processing of a Tcl command it is legal to make nested
+calls to evaluate other commands (this is how conditionals, loops,
+and procedures are implemented).
+If a code other than
+\fBTCL_OK\fR is returned from a nested \fBTcl_Eval\fR invocation, then the
+caller should normally return immediately, passing that same
+return code back to its caller, and so on until the top-level application is
+reached.  A few commands, like \fBfor\fR, will check for certain
+return codes, like \fBTCL_BREAK\fR and \fBTCL_CONTINUE\fR, and process them
+specially without returning.
+.PP
+\fBTcl_Eval\fR keeps track of how many nested Tcl_Eval invocations are
+in progress for \fIinterp\fR.
+If a code of \fBTCL_RETURN\fR, \fBTCL_BREAK\fR, or \fBTCL_CONTINUE\fR is
+about to be returned from the topmost \fBTcl_Eval\fR invocation for
+\fIinterp\fR, then \fBTcl_Eval\fR converts the return code to \fBTCL_ERROR\fR
+and sets \fIinterp->result\fR to point to an error message indicating that
+the \fBreturn\fR, \fBbreak\fR, or \fBcontinue\fR command was
+invoked in an inappropriate place.  This means that top-level
+applications should never see a return code from \fBTcl_Eval\fR other then
+\fBTCL_OK\fR or \fBTCL_ERROR\fR.

+.SH DESCRIPTION
+.PP
+These four procedures all evaluate an expression, returning
+the result in one of four different forms.
+The expression is given by the \fIstring\fR argument, and it
+can have any of the forms accepted by the \fBexpr\fR command.
+The \fIinterp\fR argument refers to an interpreter used to
+evaluate the expression (e.g. for variables and nested Tcl
+commands) and to return error information.  \fIInterp->result\fR
+is assumed to be initialized in the standard fashion when any
+of the procedures are invoked.
+.PP
+For all of these procedures the return value is a standard
+Tcl result:  \fBTCL_OK\fR means the expression was succesfully
+evaluated, and \fBTCL_ERROR\fR means that an error occurred while
+evaluating the expression.  If \fBTCL_ERROR\fR is returned then
+\fIinterp->result\fR will hold a message describing the error.
+If an error occurs while executing a Tcl command embedded in
+the expression then that error will be returned.
+.PP
+If the expression is successfully evaluated, then its value is
+returned in one of four forms, depending on which procedure
+is invoked.
+\fBTcl_ExprLong\fR stores an integer value at \fI*longPtr\fR.
+If the expression's actual value is a floating-point number,
+then it is truncated to an integer.
+If the expression's actual value is a non-numeric string then
+an error is returned.
+.PP
+\fBTcl_ExprDouble\fR stores a floating-point value at \fI*doublePtr\fR.
+If the expression's actual value is an integer, it is converted to
+floating-point.
+If the expression's actual value is a non-numeric string then
+an error is returned.
+.PP
+\fBTcl_ExprBoolean\fR stores a 0/1 integer value at \fI*booleanPtr\fR.
+If the expression's actual value is an integer or floating-point
+number, then \fBTcl_ExprBoolean\fR stores 0 at \fI*booleanPtr\fR if
+the value was zero and 1 otherwise.
+.VS
+If the expression's actual value is a non-numeric string then
+it must be one of the values accepted by \fBTcl_GetBoolean\fR,
+such as ``yes'' or ``no'', or else an error occurs.
+.VE
+.PP
+\fBTcl_ExprString\fR returns the value of the expression as a
+string stored in \fIinterp->result\fR.
+.VS
+If the expression's actual value is an integer
+then \fBTcl_ExprString\fR converts it to a string using \fBsprintf\fR
+with a ``%d'' converter.
+If the expression's actual value is a floating-point
+number, then \fBTcl_ExprString\fR calls \fBTcl_PrintDouble\fR
+to convert it to a string.

+.SH DESCRIPTION
+.PP
+These procedures convert from strings to integers or double-precision
+floating-point values or booleans (represented as 0- or 1-valued
+integers).  Each of the procedures takes a \fIstring\fR argument,
+converts it to an internal form of a particular type, and stores
+the converted value at the location indicated by the procedure's
+third argument.  If all goes well, each of the procedures returns
+TCL_OK.  If \fIstring\fR doesn't have the proper syntax for the
+desired type then TCL_ERROR is returned, an error message is left
+in \fIinterp->result\fR, and nothing is stored at *\fIintPtr\fR
+or *\fIdoublePtr\fR or *\fIboolPtr\fR.
+.PP
+\fBTcl_GetInt\fR expects \fIstring\fR to consist of a collection
+of integer digits, optionally signed and optionally preceded by
+white space.  If the first two characters of \fIstring\fR are ``0x''
+then \fIstring\fR is expected to be in hexadecimal form;  otherwise,
+if the first character of \fIstring\fR is ``0'' then \fIstring\fR
+is expected to be in octal form;  otherwise, \fIstring\fR is
+expected to be in decimal form.
+.PP
+\fBTcl_GetDouble\fR expects \fIstring\fR to consist of a floating-point
+number, which is:  white space;  a sign; a sequence of digits;  a
+decimal point;  a sequence of digits;  the letter ``e'';  and a
+signed decimal exponent.  Any of the fields may be omitted, except that
+the digits either before or after the decimal point must be present
+and if the ``e'' is present then it must be followed by the
+exponent number.
+.PP
+\fBTcl_GetBoolean\fR expects \fIstring\fR to specify a boolean
+value.  If \fIstring\fR is any of \fB0\fR, \fBfalse\fR,
+\fBno\fR, or \fBoff\fR, then \fBTcl_GetBoolean\fR stores a zero
+value at \fI*boolPtr\fR.
+If \fIstring\fR is any of \fB1\fR, \fBtrue\fR, \fByes\fR, or \fBon\fR,
+then 1 is stored at \fI*boolPtr\fR.
+Any of these values may be abbreviated, and upper-case spellings
+are also acceptable.

+.BE
+
+.SH DESCRIPTION
+.PP
+A hash table consists of zero or more entries, each consisting of
+a key and a value.
+Given the key for an entry, the hashing routines can very quickly
+locate the entry, and hence its value.
+There may be at most one entry in a hash table with a
+particular key, but many entries may have the same value.
+Keys can take one of three forms:  strings,
+one-word values, or integer arrays.
+All of the keys in a given table have the same form, which is
+specified when the table is initialized.
+.PP
+The value of a hash table entry can be anything that fits in
+the same space as a ``char *'' pointer.
+Values for hash table entries are managed entirely by clients,
+not by the hash module itself.
+Typically each entry's value is a pointer to a data structure
+managed by client code.
+.PP
+Hash tables grow gracefully as the number of entries increases,
+so that there are always less than three entries per hash bucket,
+on average.
+This allows for fast lookups regardless of the number of entries
+in a table.
+.PP
+\fBTcl_InitHashTable\fR initializes a structure that describes
+a new hash table.
+The space for the structure is provided by the caller, not by
+the hash module.
+The value of \fIkeyType\fR indicates what kinds of keys will
+be used for all entries in the table.  \fIKeyType\fR must have
+one of the following values:
+.IP \fBTCL_STRING_KEYS\fR 25
+Keys are null-terminated ASCII strings.
+They are passed to hashing routines using the address of the
+first character of the string.
+.IP \fBTCL_ONE_WORD_KEYS\fR 25
+Keys are single-word values;  they are passed to hashing routines
+and stored in hash table entries as ``char *'' values.
+The pointer value is the key;  it need not (and usually doesn't)
+actually point to a string.
+.IP \fIother\fR 25
+If \fIkeyType\fR is not TCL_STRING_KEYS or TCL_ONE_WORD_KEYS,
+then it must be an integer value greater than 1.
+In this case the keys will be arrays of ``int'' values, where
+\fIkeyType\fR gives the number of ints in each key.
+This allows structures to be used as keys.
+All keys must have the same size.
+Array keys are passed into hashing functions using the address
+of the first int in the array.
+.PP
+\fBTcl_DeleteHashTable\fR deletes all of the entries in a hash
+table and frees up the memory associated with the table's
+bucket array and entries.
+It does not free the actual table structure (pointed to
+by \fItablePtr\fR), since that memory is assumed to be managed
+by the client.
+\fBTcl_DeleteHashTable\fR also does not free or otherwise
+manipulate the values of the hash table entries.
+If the entry values point to dynamically-allocated memory, then
+it is the client's responsibility to free these structures
+before deleting the table.
+.PP
+\fBTcl_CreateHashEntry\fR locates the entry corresponding to a
+particular key, creating a new entry in the table if there
+wasn't already one with the given key.
+If an entry already existed with the given key then \fI*newPtr\fR
+is set to zero.
+If a new entry was created, then \fI*newPtr\fR is set to a non-zero
+value and the value of the new entry will be set to zero.
+The return value from \fBTcl_CreateHashEntry\fR is a pointer to
+the entry, which may be used to retrieve and modify the entry's
+value or to delete the entry from the table.
+.PP
+\fBTcl_DeleteHashEntry\fR will remove an existing entry from a
+table.
+The memory associated with the entry itself will be freed, but
+the client is responsible for any cleanup associated with the
+entry's value, such as freeing a structure that it points to.
+.PP
+\fBTcl_FindHashEntry\fR is similar to \fBTcl_CreateHashEntry\fR
+except that it doesn't create a new entry if the key doesn't exist;
+instead, it returns NULL as result.
+.PP
+\fBTcl_GetHashValue\fR and \fBTcl_SetHashValue\fR are used to
+read and write an entry's value, respectively.
+Values are stored and retrieved as type ``ClientData'', which is
+large enough to hold a pointer value.  On almost all machines this is
+large enough to hold an integer value too.
+.PP
+\fBTcl_GetHashKey\fR returns the key for a given hash table entry,
+either as a pointer to a string, a one-word (``char *'') key, or
+as a pointer to the first word of an array of integers, depending
+on the \fIkeyType\fR used to create a hash table.
+In all cases \fBTcl_GetHashKey\fR returns a result with type
+``char *''.
+When the key is a string or array, the result of \fBTcl_GetHashKey\fR
+points to information in the table entry;  this information will
+remain valid until the entry is deleted or its table is deleted.
+.PP
+\fBTcl_FirstHashEntry\fR and \fBTcl_NextHashEntry\fR may be used
+to scan all of the entries in a hash table.
+A structure of type ``Tcl_HashSearch'', provided by the client,
+is used to keep track of progress through the table.
+\fBTcl_FirstHashEntry\fR initializes the search record and
+returns the first entry in the table (or NULL if the table is
+empty).
+Each susequent call to \fBTcl_NextHashEntry\fR returns the
+next entry in the table or
+NULL if the end of the table has been reached.
+A call to \fBTcl_FirstHashEntry\fR followed by calls to
+\fBTcl_NextHashEntry\fR will return each of the entries in
+the table exactly once, in an arbitrary order.
+It is unadvisable to modify the structure of the table, e.g.
+by creating or deleting entries, while the search is in
+progress.
+.PP
+\fBTcl_HashStats\fR returns a dynamically-allocated string with
+overall information about a hash table, such as the number of
+entries it contains, the number of buckets in its hash array,
+and the utilization of the buckets.
+It is the caller's responsibility to free the result string
+by passing it to \fBfree\fR.
+.PP
+The header file \fBtcl.h\fR defines the actual data structures
+used to implement hash tables.
+This is necessary so that clients can allocate Tcl_HashTable
+structures and so that macros can be used to read and write
+the values of entries.
+However, users of the hashing routines should never refer directly
+to any of the fields of any of the hash-related data structures;
+use the procedures and macros defined here.

+.sp
+typedef struct {
+	char *\fIresult\fR;
+	Tcl_FreeProc *\fIfreeProc\fR;
+	int \fIerrorLine\fR;
+} Tcl_Interp;
+
+typedef void Tcl_FreeProc(char *\fIblockPtr\fR);
+.BE
+
+.SH DESCRIPTION
+.PP
+The \fBTcl_CreateInterp\fR procedure returns a pointer to a Tcl_Interp
+structure.  This pointer is then passed into other Tcl procedures
+to process commands in the interpreter and perform other operations
+on the interpreter.  Interpreter structures contain many many fields
+that are used by Tcl, but only three that may be accessed by
+clients:  \fIresult\fR, \fIfreeProc\fR, and \fIerrorLine\fR.
+.PP
+The \fIresult\fR and \fIfreeProc\fR fields are used to return
+results or error messages from commands.
+This information is returned by command procedures back to \fBTcl_Eval\fR,
+and by \fBTcl_Eval\fR back to its callers.
+The \fIresult\fR field points to the string that represents the
+result or error message, and the \fIfreeProc\fR field tells how
+to dispose of the storage for the string when it isn't needed anymore.
+The easiest way for command procedures to manipulate these
+fields is to call procedures like \fBTcl_SetResult\fR
+or \fBTcl_AppendResult\fR;  they
+will hide all the details of managing the fields.
+The description below is for those procedures that manipulate the
+fields directly.
+.PP
+Whenever a command procedure returns, it must ensure
+that the \fIresult\fR field of its interpreter points to the string
+being returned by the command.
+The \fIresult\fR field must always point to a valid string.
+If a command wishes to return no result then \fIinterp->result\fR
+should point to an empty string.
+Normally, results are assumed to be statically allocated,
+which means that the contents will not change before the next time
+\fBTcl_Eval\fR is called or some other command procedure is invoked.
+In this case, the \fIfreeProc\fR field must be zero.
+Alternatively, a command procedure may dynamically
+allocate its return value (e.g. using \fBmalloc\fR)
+and store a pointer to it in \fIinterp->result\fR.
+In this case, the command procedure must also set \fIinterp->freeProc\fR
+to the address of a procedure that can free the value (usually \fBfree\fR).
+If \fIinterp->freeProc\fR is non-zero, then Tcl will call \fIfreeProc\fR
+to free the space pointed to by \fIinterp->result\fR before it
+invokes the next command.
+If a client procedure overwrites \fIinterp->result\fR when
+\fIinterp->freeProc\fR is non-zero, then it is responsible for calling
+\fIfreeProc\fR to free the old \fIinterp->result\fR (the \fBTcl_FreeResult\fR
+macro should be used for this purpose).
+.PP
+\fIFreeProc\fR should have arguments and result that match the
+\fBTcl_FreeProc\fR declaration above:  it receives a single
+argument which is a pointer to the result value to free.
+In most applications \fBfree\fR is the only non-zero value ever
+used for \fIfreeProc\fR.
+However, an application may store a different procedure address
+in \fIfreeProc\fR in order to use an alternate memory allocator
+or in order to do other cleanup when the result memory is freed.
+.PP
+As part of processing each command, \fBTcl_Eval\fR initializes
+\fIinterp->result\fR
+and \fIinterp->freeProc\fR just before calling the command procedure for
+the command.  The \fIfreeProc\fR field will be initialized to zero,
+and \fIinterp->result\fR will point to an empty string.  Commands that
+do not return any value can simply leave the fields alone.
+Furthermore, the empty string pointed to by \fIresult\fR is actually
+part of an array of \fBTCL_RESULT_SIZE\fR characters (approximately 200).
+If a command wishes to return a short string, it can simply copy
+it to the area pointed to by \fIinterp->result\fR.  Or, it can use
+the sprintf procedure to generate a short result string at the location
+pointed to by \fIinterp->result\fR.
+.PP
+It is a general convention in Tcl-based applications that the result
+of an interpreter is normally in the initialized state described
+in the previous paragraph.
+Procedures that manipulate an interpreter's result (e.g. by
+returning an error) will generally assume that the result
+has been initialized when the procedure is called.
+If such a procedure is to be called after the result has been
+changed, then \fBTcl_ResetResult\fR should be called first to
+reset the result to its initialized state.
+.PP
+The \fIerrorLine\fR
+field is valid only after \fBTcl_Eval\fR returns

+Type of C variable.  Must be one of TCL_LINK_INT, TCL_LINK_DOUBLE,
+TCL_LINK_BOOLEAN, or TCL_LINK_STRING, optionally OR'ed with
+TCL_LINK_READ_ONLY to make Tcl variable read-only.
+.ad
+.BE
+
+.SH DESCRIPTION
+.PP
+\fBTcl_LinkVar\fR uses variable traces to keep the Tcl variable
+named by \fIvarName\fR in sync with the C variable at the address
+given by \fIaddr\fR.
+Whenever the Tcl variable is read the value of the C variable will
+be returned, and whenever the Tcl variable is written the C
+variable will be updated to have the same value.
+\fBTcl_LinkVar\fR normally returns TCL_OK;  if an error occurs
+while setting up the link (e.g. because \fIvarName\fR is the
+name of array) then TCL_ERROR is returned and \fIinterp->result\fR
+contains an error message.
+.PP
+The \fItype\fR argument specifies the type of the C variable,
+and must have one of the following values, optionally OR'ed with
+TCL_LINK_READ_ONLY:
+.TP
+\fBTCL_LINK_INT\fR
+The C variable is of type \fBint\fR.
+Any value written into the Tcl variable must have a proper integer
+form acceptable to \fBTcl_GetInt\fR;  attempts to write
+non-integer values into \fIvarName\fR will be rejected with
+Tcl errors.
+.TP
+\fBTCL_LINK_DOUBLE\fR
+The C variable is of type \fBdouble\fR.
+Any value written into the Tcl variable must have a proper real
+form acceptable to \fBTcl_GetDouble\fR;  attempts to write
+non-real values into \fIvarName\fR will be rejected with
+Tcl errors.
+.TP
+\fBTCL_LINK_BOOLEAN\fR
+The C variable is of type \fBint\fR.
+If its value is zero then it will read from Tcl as ``0'';
+otherwise it will read from Tcl as ``1''.
+Whenver \fIvarName\fR is
+modified, the C variable will be set to a 0 or 1 value.
+Any value written into the Tcl variable must have a proper boolean
+form acceptable to \fBTcl_GetBoolean\fR;  attempts to write
+non-boolean values into \fIvarName\fR will be rejected with
+Tcl errors.
+.TP
+\fBTCL_LINK_STRING\fR
+The C variable is of type \fBchar *\fR.
+If its value is not null then it must be a pointer to a string
+allocated with \fBmalloc\fR.
+Whenever the Tcl variable is modified the current C string will be
+freed and new memory will be allocated to hold a copy of the variable's
+new value.
+If the C variable contains a null pointer then the Tcl variable
+will read as ``NULL''.
+.PP
+If the TCL_LINK_READ_ONLY flag is present in \fItype\fR then the
+variable will be read-only from Tcl, so that its value can only be
+changed by modifying the C variable.
+Attempts to write the variable from Tcl will be rejected with errors.

+%g would generate an integer with no decimal point, \fBTcl_PrintDouble\fR
+adds ``.0'').  Second, the number of significant digits printed at
+\fIdst\fR is controlled by the \fBtcl_precision\fR variable in
+\fIinterp\fR;  if \fBtcl_precision\fR is undefined then 6 significant

+.BE
+
+.SH DESCRIPTION
+.PP
+The procedures described here are utilities for setting the
+result/error string in a Tcl interpreter.
+.PP
+\fBTcl_SetResult\fR
+arranges for \fIstring\fR to be the return string for the current Tcl
+command in \fIinterp\fR, replacing any existing result.
+If \fIfreeProc\fR is \fBTCL_STATIC\fR it means that \fIstring\fR
+refers to an area of static storage that is guaranteed not to be
+modified until at least the next call to \fBTcl_Eval\fR.
+If \fIfreeProc\fR
+is \fBTCL_DYNAMIC\fR it means that \fIstring\fR was allocated with a call
+to \fBmalloc()\fR and is now the property of the Tcl system.
+\fBTcl_SetResult\fR will arrange for the string's storage to be
+released by calling \fBfree()\fR when it is no longer needed.
+If \fIfreeProc\fR is \fBTCL_VOLATILE\fR it means that \fIstring\fR
+points to an area of memory that is likely to be overwritten when
+\fBTcl_SetResult\fR returns (e.g. it points to something in a stack frame).
+In this case \fBTcl_SetResult\fR will make a copy of the string in
+dynamically allocated storage and arrange for the copy to be the
+return string for the current Tcl command.
+.PP
+If \fIfreeProc\fR isn't one of the values \fBTCL_STATIC\fR,
+\fBTCL_DYNAMIC\fR, and \fBTCL_VOLATILE\fR, then it is the address
+of a procedure that Tcl should call to free the string.
+This allows applications to use non-standard storage allocators.
+When Tcl no longer needs the storage for the string, it will
+call \fIfreeProc\fR.  \fIFreeProc\fR should have arguments and
+result that match the type \fBTcl_FreeProc\fR:
+.nf
+.RS
+
+typedef void Tcl_FreeProc(char *\fIblockPtr\fR);
+
+.RE
+.fi
+When \fIfreeProc\fR is called, its \fIblockPtr\fR will be set to
+the value of \fIstring\fR passed to \fBTcl_SetResult\fR.
+.PP
+If \fIstring\fR is \fBNULL\fR, then \fIfreeProc\fR is ignored
+and \fBTcl_SetResult\fR
+re-initializes \fIinterp\fR's result to point to the pre-allocated result
+area, with an empty string in the result area.
+.PP
+If \fBTcl_SetResult\fR is called at a time when \fIinterp\fR holds a
+result, \fBTcl_SetResult\fR does whatever is necessary to dispose
+of the old result (see the \fBTcl_Interp\fR manual entry for details
+on this).
+.PP
+\fBTcl_AppendResult\fR makes it easy to build up Tcl results in pieces.
+It takes each of its \fIstring\fR arguments and appends them in order
+to the current result associated with \fIinterp\fR.
+If the result is in its initialized empty state (e.g. a command procedure
+was just invoked or \fBTcl_ResetResult\fR was just called),
+then \fBTcl_AppendResult\fR sets the result to the concatenation of
+its \fIstring\fR arguments.
+\fBTcl_AppendResult\fR may be called repeatedly as additional pieces
+of the result are produced.
+\fBTcl_AppendResult\fR takes care of all the
+storage management issues associated with managing \fIinterp\fR's
+result, such as allocating a larger result area if necessary.
+Any number of \fIstring\fR arguments may be passed in a single
+call;  the last argument in the list must be a NULL pointer.
+.PP
+\fBTcl_AppendElement\fR is similar to \fBTcl_AppendResult\fR in
+that it allows results to be built up in pieces.
+However, \fBTcl_AppendElement\fR takes only a single \fIstring\fR
+argument and it appends that argument to the current result
+as a proper Tcl list element.
+\fBTcl_AppendElement\fR adds backslashes or braces if necessary
+to ensure that \fIinterp\fR's result can be parsed as a list and that
+\fIstring\fR will be extracted as a single element.
+Under normal conditions, \fBTcl_AppendElement\fR will add a space
+character to \fIinterp\fR's result just before adding the new
+list element, so that the list elements in the result are properly
+separated.
+.VS
+However if the new list element is the first in a list or sub-list
+(i.e. \fIinterp\fR's current result is empty, or consists of the
+single character ``{'', or ends in the characters `` {'') then no
+space is added.
+.VE
+.PP
+\fBTcl_ResetResult\fR clears the result for \fIinterp\fR,
+freeing the memory associated with it if the current result was
+dynamically allocated.
+It leaves the result in its normal initialized state with
+\fIinterp->result\fR pointing to a static buffer containing
+\fBTCL_RESULT_SIZE\fR characters, of which the first character
+is zero.
+\fBTcl_ResetResult\fR also clears the error state managed by
+\fBTcl_AddErrorInfo\fR and \fBTcl_SetErrorCode\fR.
+.PP
+\fBTcl_FreeResult\fR is a macro that performs part of the work
+of \fBTcl_ResetResult\fR.
+It frees up the memory associated with \fIinterp\fR's result
+and sets \fIinterp->freeProc\fR to zero, but it doesn't
+change \fIinterp->result\fR or clear error state.
+\fBTcl_FreeResult\fR is most commonly used when a procedure
+is about to replace one result value with another.

+.SH DESCRIPTION
+.PP
+These procedures may be used to create, modify, read, and delete
+Tcl variables from C code.
+\fBTcl_SetVar\fR and \fBTcl_SetVar2\fR will create a new variable
+or modify an existing one.
+Both of these procedures set the given variable to the value
+given by \fInewValue\fR, and they return a pointer to a
+copy of the variable's new value, which is stored in Tcl's
+variable structure.
+Tcl keeps a private copy of the variable's value, so the caller
+may change \fInewValue\fR after these procedures return without
+affecting the value of the variable.
+If an error occurs in setting the variable (e.g. an array
+variable is referenced without giving an index into the array),
+then NULL is returned.
+.PP
+The name of the variable may be specified in either of two ways.
+If \fBTcl_SetVar\fR is called, the variable name is given as
+a single string, \fIvarName\fR.
+If \fIvarName\fR contains an open parenthesis and ends with a
+close parenthesis, then the value between the parentheses is
+treated as an index (which can have any string value) and
+the characters before the first open
+parenthesis are treated as the name of an array variable.
+If \fIvarName\fR doesn't have parentheses as described above, then
+the entire string is treated as the name of a scalar variable.
+If \fBTcl_SetVar2\fR is called, then the array name and index
+have been separated by the caller into two separate strings,
+\fIname1\fR and \fIname2\fR respectively;  if \fIname2\fR is
+zero it means that a scalar variable is being referenced.
+.PP
+The \fIflags\fR argument may be used to specify any of several
+options to the procedures.
+It consists of an OR-ed combination of any of the following
+bits:
+.IP TCL_GLOBAL_ONLY
+Under normal circumstances the procedures look up variables
+at the current level of procedure call for \fIinterp\fR, or
+at global level if there is no call active.
+However, if this bit is set in \fIflags\fR then the variable
+is looked up at global level even if there is a procedure
+call active.
+.IP TCL_LEAVE_ERR_MSG
+If an error is returned and this bit is set in \fIflags\fR, then
+an error message will be left in \fI\%interp->result\fR.  If this
+flag bit isn't set then no error message is left (\fI\%interp->result\fR
+will not be modified).
+.IP TCL_APPEND_VALUE
+If this bit is set then \fInewValue\fR is appended to the current
+value, instead of replacing it.
+If the variable is currently undefined, then this bit is ignored.
+.IP TCL_LIST_ELEMENT
+If this bit is set, then \fInewValue\fR is converted to a valid
+Tcl list element before setting (or appending to) the variable.
+A separator space is appended before the new list element unless
+.VS
+the list element is going to be the first element in a list or
+sublist (i.e. the variable's current value is empty, or contains
+the single character ``{'', or ends in `` }'').
+.VE
+.PP
+\fBTcl_GetVar\fR and \fBTcl_GetVar2\fR return the current value
+of a variable.
+The arguments to these procedures are treated in the same way
+as the arguments to \fBTcl_SetVar\fR and \fBTcl_SetVar2\fR.
+Under normal circumstances, the return value is a pointer
+to the variable's value (which is stored in Tcl's variable
+structure and will not change before the next call to \fBTcl_SetVar\fR
+or \fBTcl_SetVar2\fR).
+The only bits of \fIflags\fR that are used are TCL_GLOBAL_ONLY
+and TCL_LEAVE_ERR_MSG, both of
+which have
+the same meaning as for \fBTcl_SetVar\fR.
+If an error occurs in reading the variable (e.g. the variable
+doesn't exist or an array element is specified for a scalar
+variable), then NULL is returned.
+.PP
+\fBTcl_UnsetVar\fR and \fBTcl_UnsetVar2\fR may be used to remove
+a variable, so that future calls to \fBTcl_GetVar\fR or \fBTcl_GetVar2\fR
+for the variable will return an error.
+The arguments to these procedures are treated in the same way
+as the arguments to \fBTcl_GetVar\fR and \fBTcl_GetVar2\fR.
+.VS
+If the variable is successfully removed then TCL_OK is returned.
+If the variable cannot be removed because it doesn't exist then
+TCL_ERROR is returned.
+.VE
+If an array element is specified, the given element is removed
+but the array remains.
+If an array name is specified without an index, then the entire
+array is removed.

+
+.SH DESCRIPTION
+.PP
+These procedures may be used to disassemble and reassemble Tcl lists.
+\fBTcl_SplitList\fR breaks a list up into its constituent elements,
+returning an array of pointers to the elements using
+\fIargcPtr\fR and \fIargvPtr\fR.
+While extracting the arguments, \fBTcl_SplitList\fR obeys the usual
+rules for backslash substitutions and braces.  The area of
+memory pointed to by \fI*argvPtr\fR is dynamically allocated;  in
+addition to the array of pointers, it
+also holds copies of all the list elements.  It is the caller's
+responsibility to free up all of this storage by calling
+.DS
+\fBfree\fR((char *) \fI*argvPtr\fR)
+.DE
+when the list elements are no longer needed.
+.PP
+\fBTcl_SplitList\fR normally returns \fBTCL_OK\fR, which means the list was
+successfully parsed.
+If there was a syntax error in \fIlist\fR, then \fBTCL_ERROR\fR is returned
+and \fIinterp->result\fR will point to an error message describing the
+problem.
+If \fBTCL_ERROR\fR is returned then no memory is allocated and \fI*argvPtr\fR
+is not modified.
+.PP
+\fBTcl_Merge\fR is the inverse of \fBTcl_SplitList\fR:  it
+takes a collection of strings given by \fIargc\fR
+and \fIargv\fR and generates a result string
+that has proper list structure.
+This means that commands like \fBindex\fR may be used to
+extract the original elements again.
+In addition, if the result of \fBTcl_Merge\fR is passed to \fBTcl_Eval\fR,
+it will be parsed into \fIargc\fR words whose values will
+be the same as the \fIargv\fR strings passed to \fBTcl_Merge\fR.
+\fBTcl_Merge\fR will modify the list elements with braces and/or
+backslashes in order to produce proper Tcl list structure.
+The result string is dynamically allocated
+using \fBmalloc()\fR;  the caller must eventually release the space
+using \fBfree()\fR.
+.PP
+If the result of \fBTcl_Merge\fR is passed to \fBTcl_SplitList\fR,
+the elements returned by \fBTcl_SplitList\fR will be identical to
+those passed into \fBTcl_Merge\fR.
+However, the converse is not true:  if \fBTcl_SplitList\fR
+is passed a given string, and the resulting \fIargc\fR and
+\fIargv\fR are passed to \fBTcl_Merge\fR, the resulting string
+may not be the same as the original string passed to \fBTcl_SplitList\fR.
+This is because \fBTcl_Merge\fR may use backslashes and braces
+differently than the original string.
+.PP
+\fBTcl_ScanElement\fR and \fBTcl_ConvertElement\fR are the
+procedures that do all of the real work of \fBTcl_Merge\fR.
+\fBTcl_ScanElement\fR scans its \fIsrc\fR argument
+and determines how to use backslashes and braces
+when converting it to a list element.
+It returns an overestimate of the number of characters
+required to represent \fIsrc\fR as a list element, and
+it stores information in \fI*flagsPtr\fR that is needed
+by \fBTcl_ConvertElement\fR.
+.PP
+\fBTcl_ConvertElement\fR is a companion procedure to \fBTcl_ScanElement\fR.
+It does the actual work of converting a string to a list element.
+Its \fIflags\fR argument must be the same as the value returned
+by \fBTcl_ScanElement\fR.
+\fBTcl_ConvertElement\fR writes a proper list element to memory
+starting at *\fIdst\fR and returns a count of the total number
+of characters written, which will be no more than the result
+returned by \fBTcl_ScanElement\fR.
+\fBTcl_ConvertElement\fR writes out only the actual list element
+without any leading or trailing spaces: it is up to the caller to
+include spaces between adjacent list elements.
+.PP
+\fBTcl_ConvertElement\fR uses one of two different approaches to
+handle the special characters in \fIsrc\fR.  Wherever possible, it
+handles special characters by surrounding the string with braces.
+This produces clean-looking output, but can't be used in some situations,
+such as when \fIsrc\fR contains unmatched braces.
+In these situations, \fBTcl_ConvertElement\fR handles special
+characters by generating backslash sequences for them.
+The caller may insist on the second approach by OR-ing the
+flag value returned by \fBTcl_ScanElement\fR with
+\fBTCL_DONT_USE_BRACES\fR.
+Although this will produce an uglier result, it is useful in some
+special situations, such as when \fBTcl_ConvertElement\fR is being
+used to generate a portion of an argument for a Tcl command.
+In this case, surrounding \fIsrc\fR with curly braces would cause
+the command not to be parsed correctly.

+.BS
+.SH NAME
+Tcl \- Summary of Tcl language syntax.
+.BE
+
+.SH DESCRIPTION
+.LP
+The following rules define the syntax and semantics of the Tcl language:
+.IP [1]
+A Tcl script is a string containing one or more commands.
+Semi-colons and newlines are command separators unless quoted as
+described below.
+Close brackets are command terminators during command substitution
+(see below) unless quoted.
+.IP [2]
+A command is evaluated in two steps.
+First, the Tcl interpreter breaks the command into \fIwords\fR
+and performs substitutions as described below.
+These substitutions are performed in the same way for all
+commands.
+The first word is used to locate a command procedure to
+carry out the command, then all of the words of the command are
+passed to the command procedure.
+The command procedure is free to interpret each of its words
+in any way it likes, such as an integer, variable name, list,
+or Tcl script.
+Different commands interpret their words differently.
+.IP [3]
+Words of a command are separated by white space (except for
+newlines, which are command separators).
+.IP [4]
+If the first character of a word is double-quote (``"'') then
+the word is terminated by the next double-quote character.
+If semi-colons, close brackets, or white space characters
+(including newlines) appear between the quotes then they are treated
+as ordinary characters and included in the word.
+Command substitution, variable substitution, and backslash substitution
+are performed on the characters between the quotes as described below.
+The double-quotes are not retained as part of the word.
+.IP [5]
+If the first character of a word is an open brace (``{'') then
+the word is terminated by the matching close brace (``}'').
+Braces nest within the word: for each additional open
+brace there must be an additional close brace (however,
+if an open brace or close brace within the word is
+quoted with a backslash then it is not counted in locating the
+matching close brace).
+No substitutions are performed on the characters between the
+braces except for backslash-newline substitutions described
+below, nor do semi-colons, newlines, close brackets,
+or white space receive any special interpretation.
+The word will consist of exactly the characters between the
+outer braces, not including the braces themselves.
+.IP [6]
+If a word contains an open bracket (``['') then Tcl performs
+\fIcommand substitution\fR.
+To do this it invokes the Tcl interpreter recursively to process
+the characters following the open bracket as a Tcl script.
+The script may contain any number of commands and must be terminated
+by a close bracket (``]'').
+The result of the script (i.e. the result of its last command) is
+substituted into the word in place of the brackets and all of the
+characters between them.
+There may be any number of command substitutions in a single word.
+Command substitution is not performed on words enclosed in braces.
+.IP [7]
+If a word contains a dollar-sign (``$'') then Tcl performs \fIvariable
+substitution\fR:  the dollar-sign and the following characters are
+replaced in the word by the value of a variable.
+Variable substition may take any of the following forms:
+.RS
+.TP 15
+\fB$\fIname\fR
+\fIName\fR is the name of a scalar variable;  the name is terminated
+by any character that isn't a letter, digit, or underscore.
+.TP 15
+\fB$\fIname\fB(\fIindex\fB)\fR
+\fIName\fR gives the name of an array variable and \fIindex\fR gives
+the name of an element within that array.
+\fIName\fR must contain only letters, digits, and underscores.
+Command substitutions, variable substitutions, and backslash
+substitutions are performed on the characters of \fIindex\fR.
+.TP 15
+\fB${\fIname\fB}\fR
+\fIName\fR is the name of a scalar variable.  It may contain any
+characters whatsoever except for close braces.
+.RE
+.LP
+There may be any number of variable substitutions in a single word.
+Variable substitution is not performed on words enclosed in braces.
+.IP [8]
+If a backslash (``\e'') appears within a word then
+\fIbackslash substitution\fR occurs.
+.VS
+In all cases but those described below the backslash is dropped and
+the following character is treated as an ordinary
+character and included in the word.
+.VE
+This allows characters such as double quotes, close brackets,
+and dollar signs to be included in words without triggering
+special processing.
+The following table lists the backslash sequences that are
+handled specially, along with the value that replaces each sequence.
+.RS

+.TP 6
+\e\fB<newline>\fIwhiteSpace\fR\fR
+.VS
+A single space character replaces the backslash, newline, and all
+white space after the newline.
+This backslash sequence is unique in that it is replaced in a separate
+pre-pass before the command is actually parsed.
+This means that it will be replaced even when it occurs between
+braces, and the resulting space will be treated as a word separator
+if it isn't in braces or quotes.
+.VE
+.TP 6
+\e\e
+Backslash (``\e'').
+.TP 6
+\e\fIooo\fR
+The digits \fIooo\fR (one, two, or three of them) give the octal value of
+the character.
+.TP 6
+\e\fBx\fIhh\fR
+.VS
+The hexadecimal digits \fIhh\fR give the hexadecimal value of
+the character.  Any number of digits may be present.
+.VE
+.RE
+.LP
+Backslash substitution is not performed on words enclosed in braces,
+except for backslash-newline as described above.
+.IP [9]
+If a hash character (``#'') appears at a point where Tcl is
+expecting the first character of the first word of a command,
+then the hash character and the characters that follow it, up
+through the next newline, are treated as a comment and ignored.
+The comment character only has significance when it appears
+at the beginning of a command.
+.IP [10]
+Each character is processed exactly once by the Tcl interpreter
+as part of creating the words of a command.
+For example, if variable substition occurs then no further
+substitions are performed on the value of the variable;  the
+value is inserted into the word verbatim.
+If command substitution occurs then the nested command is
+processed entirely by the recursive call to the Tcl interpreter;
+no substitutions are perfomed before making the recursive
+call and no additional substitutions are performed on the result
+of the nested script.
+.IP [11]
+Substitutions do not affect the word boundaries of a command.
+For example, during variable substitution the entire value of
+the variable becomes part of a single word, even if the variable's
+value contains spaces.

+.SH DESCRIPTION
+.PP
+This utility procedure does tilde substition.  If \fIname\fR doesn't
+start with a ``~'' character, then the procedure returns \fIname\fR.
+If \fIname\fR does start with a tilde, then \fBTcl_TildeSubst\fR
+returns a new string identical to \fIname\fR except that the first
+element of \fIname\fR is replaced with the location of the home
+directory for the given user.  The substitution is carried out in
+the same way that it would be done by \fIcsh\fR.  If the tilde is
+followed immediately by a slash, then the \fB$HOME\fR environment
+variable is substituted.  Otherwise the characters between the
+tilde and the next slash are taken as a user name, which is
+looked up in the password file;  the user's home directory is
+retrieved from the password file and substituted.
+.PP
+If
+.VS
+\fBTcl_TildeSubst\fR has to do tilde substitution then it uses
+the dynamic string at \fI*bufferPtr\fR to hold the new string it
+generates.  After \fBTcl_TildeSubst\fR returns, the caller must
+eventually invoke \fBTcl_DStringFree\fR to free up any information
+placed in \fI*bufferPtr\fR.  The caller need not know whether or
+not \fBTcl_TildeSubst\fR actually used the string;  \fBTcl_TildeSubst\fR
+initializes \fI*bufferPtr\fR even if it doesn't use it, so the call to
+\fBTcl_DStringFree\fR will be safe in either case.
+.VE
+.PP
+If an error occurs (e.g. because there was no user by the given
+name) then NULL is returned and an error message will be left
+at \fIinterp->result\fR.  It is assumed that \fIinterp->result\fR
+has been initialized in the standard way when \fBTcl_TildeSubst\fR
+is invoked.

+.BE
+
+.SH DESCRIPTION
+.PP
+\fBTcl_TraceVar\fR allows a C procedure to monitor and control
+access to a Tcl variable, so that the C procedure is invoked
+whenever the variable is read or written or unset.
+If the trace is created successfully then \fBTcl_TraceVar\fR returns
+TCL_OK.  If an error occurred (e.g. \fIvarName\fR specifies an element
+of an array, but the actual variable isn't an array) then TCL_ERROR
+is returned and an error message is left in \fIinterp->result\fR.
+.PP
+The \fIflags\fR argument to \fBTcl_TraceVar\fR indicates when the
+trace procedure is to be invoked and provides information
+for setting up the trace.  It consists of an OR-ed combination
+of any of the following values:
+.TP
+\fBTCL_GLOBAL_ONLY\fR
+Normally, the variable will be looked up at the current level of
+procedure call;  if this bit is set then the variable will be looked
+up at global level, ignoring any active procedures.
+.TP
+\fBTCL_TRACE_READS\fR
+Invoke \fIproc\fR whenever an attempt is made to read the variable.
+.TP
+\fBTCL_TRACE_WRITES\fR
+Invoke \fIproc\fR whenever an attempt is made to modify the variable.
+.TP
+\fBTCL_TRACE_UNSETS\fR
+Invoke \fIproc\fR whenever the variable is unset.
+A variable may be unset either explicitly by an \fBunset\fR command,
+or implicitly when a procedure returns (its local variables are
+automatically unset) or when the interpreter is deleted (all
+variables are automatically unset).
+.PP
+Whenever one of the specified operations occurs on the variable,
+\fIproc\fR will be invoked.
+It should have arguments and result that match the type
+\fBTcl_VarTraceProc\fR:
+.nf
+.RS
+typedef char *Tcl_VarTraceProc(
+.RS
+ClientData \fIclientData\fR,
+Tcl_Interp *\fIinterp\fR,
+char *\fIname1\fR,
+char *\fIname2\fR,
+int \fIflags\fR);
+.RE
+.RE
+.fi
+The \fIclientData\fP and \fIinterp\fP parameters will
+have the same values as those passed to \fBTcl_TraceVar\fR when the
+trace was created.
+\fIClientData\fR typically points to an application-specific
+data structure that describes what to do when \fIproc\fR
+is invoked.
+\fIName1\fR and \fIname2\fR give the name of the traced variable
+in the normal two-part form (see the description of \fBTcl_TraceVar2\fR
+below for details).
+\fIFlags\fR is an OR-ed combination of bits providing several
+pieces of information.
+One of the bits TCL_TRACE_READS, TCL_TRACE_WRITES, or TCL_TRACE_UNSETS
+will be set in \fIflags\fR to indicate which operation is being performed
+on the variable.
+The bit TCL_GLOBAL_ONLY will be set whenever the variable being
+accessed is a global one not accessible from the current level of
+procedure call:  the trace procedure will need to pass this flag
+back to variable-related procedures like \fBTcl_GetVar\fR if it
+attempts to access the variable.
+The bit TCL_TRACE_DESTROYED will be set in \fIflags\fR if the trace is
+about to be destroyed;  this information may be useful to \fIproc\fR
+so that it can clean up its own internal data structures (see
+the section TCL_TRACE_DESTROYED below for more details).
+Lastly, the bit TCL_INTERP_DESTROYED will be set if the entire
+interpreter is being destroyed.
+When this bit is set, \fIproc\fR must be especially careful in
+the things it does (see the section TCL_INTERP_DESTROYED below).
+The trace procedure's return value should normally be NULL;  see
+ERROR RETURNS below for information on other possibilities.
+.PP
+\fBTcl_UntraceVar\fR may be used to remove a trace.
+If the variable specified by \fIinterp\fR, \fIvarName\fR, and \fIflags\fR
+has a trace set with \fIflags\fR, \fIproc\fR, and
+\fIclientData\fR, then the corresponding trace is removed.
+If no such trace exists, then the call to \fBTcl_UntraceVar\fR
+has no effect.
+The same bits are valid for \fIflags\fR as for calls to \fBTcl_TraceVars\fR.
+.PP
+\fBTcl_VarTraceInfo\fR may be used to retrieve information about
+traces set on a given variable.
+The return value from \fBTcl_VarTraceInfo\fR is the \fIclientData\fR
+associated with a particular trace.
+The trace must be on the variable specified by the \fIinterp\fR,
+\fIvarName\fR, and \fIflags\fR arguments (only the TCL_GLOBAL_ONLY
+bit from \fIflags\fR is used;  other bits are ignored) and its trace procedure
+must the same as the \fIproc\fR argument.
+If the \fIprevClientData\fR argument is NULL then the return
+value corresponds to the first (most recently created) matching
+trace, or NULL if there are no matching traces.
+If the \fIprevClientData\fR argument isn't NULL, then it should
+be the return value from a previous call to \fBTcl_VarTraceInfo\fR.
+In this case, the new return value will correspond to the next
+matching trace after the one whose \fIclientData\fR matches
+\fIprevClientData\fR, or NULL if no trace matches \fIprevClientData\fR
+or if there are no more matching traces after it.
+This mechanism makes it possible to step through all of the
+traces for a given variable that have the same \fIproc\fR.
+
+.SH "TWO-PART NAMES"
+.PP
+The procedures \fBTcl_TraceVar2\fR, \fBTcl_UntraceVar2\fR, and
+\fBTcl_VarTraceInfo2\fR are identical to \fBTcl_TraceVar\fR,
+\fBTcl_UntraceVar\fR, and \fBTcl_VarTraceInfo\fR, respectively,
+except that the name of the variable has already been
+separated by the caller into two parts.
+\fIName1\fR gives the name of a scalar variable or array,
+and \fIname2\fR gives the name of an element within an
+array.
+If \fIname2\fR is NULL it means that either the variable is
+a scalar or the trace is to be set on the entire array rather
+than an individual element (see WHOLE-ARRAY TRACES below for
+more information).
+
+.SH "ACCESSING VARIABLES DURING TRACES"
+.PP
+During read and write traces, the
+trace procedure can read, write, or unset the traced
+variable using \fBTcl_GetVar2\fR, \fBTcl_SetVar2\fR, and
+other procedures.
+While \fIproc\fR is executing, traces are temporarily disabled
+for the variable, so that calls to \fBTcl_GetVar2\fR and
+\fBTcl_SetVar2\fR will not cause \fIproc\fR or other trace procedures
+to be invoked again.
+Disabling only occurs for the variable whose trace procedure
+is active;  accesses to other variables will still be traced.
+.VS
+However, if a variable is unset during a read or write trace then unset
+traces will be invoked.
+.VE
+.PP
+During unset traces the variable has already been completely
+expunged.
+It is possible for the trace procedure to read or write the
+variable, but this will be a new version of the variable.
+Traces are not disabled during unset traces as they are for
+read and write traces, but existing traces have been removed
+from the variable before any trace procedures are invoked.
+If new traces are set by unset trace procedures, these traces
+will be invoked on accesses to the variable by the trace
+procedures.
+
+.SH "CALLBACK TIMING"
+.PP
+When read tracing has been specified for a variable, the trace
+procedure will be invoked whenever the variable's value is
+read.  This includes \fBset\fR Tcl commands, \fB$\fR-notation
+in Tcl commands, and invocations of the \fBTcl_GetVar\fR
+and \fBTcl_GetVar2\fR procedures.
+\fIProc\fR is invoked just before the variable's value is
+returned.
+It may modify the value of the variable to affect what
+is returned by the traced access.
+.VS
+If it unsets the variable then the access will return an error
+just as if the variable never existed.
+.VE
+.PP
+When write tracing has been specified for a variable, the
+trace procedure will be invoked whenever the variable's value
+is modified.  This includes \fBset\fR commands\fR,
+commands that modify variables as side effects (such as
+\fBcatch\fR and \fBscan\fR), and calls to the \fBTcl_SetVar\fR
+and \fBTcl_SetVar2\fR procedures).
+\fIProc\fR will be invoked after the variable's value has been
+modified, but before the new value of the variable has been
+returned.
+It may modify the value of the variable to override the change
+and to determine the value actually returned by the traced
+access.
+.VS
+If it deletes the variable then the traced access will return
+an empty string.
+.VE
+.PP
+When unset tracing has been specified, the trace procedure
+will be invoked whenever the variable is destroyed.
+The traces will be called after the variable has been
+completely unset.
+
+.SH "WHOLE-ARRAY TRACES"
+.PP
+If a call to \fBTcl_TraceVar\fR or \fBTcl_TraceVar2\fR specifies
+the name of an array variable without an index into the array,
+then the trace will be set on the array as a whole.
+This means that \fIproc\fR will be invoked whenever any
+element of the array is accessed in the ways specified by
+\fIflags\fR.
+When an array is unset, a whole-array trace will be invoked
+just once, with \fIname1\fR equal to the name of the array
+and \fIname2\fR NULL;  it will not be invoked once for each
+element.
+
+.SH "MULTIPLE TRACES"
+.PP
+It is possible for multiple traces to exist on the same variable.
+When this happens, all of the trace procedures will be invoked on each
+access, in order from most-recently-created to least-recently-created.
+When there exist whole-array traces for an array as well as
+traces on individual elements, the whole-array traces are invoked
+before the individual-element traces.
+.VS
+If a read or write trace unsets the variable then all of the unset
+traces will be invoked but the remainder of the read and write traces
+will be skipped.
+.VE
+
+.SH "ERROR RETURNS"
+.PP
+Under normal conditions trace procedures should return NULL, indicating
+successful completion.
+If \fIproc\fR returns a non-NULL value it signifies that an
+error occurred.
+The return value must be a pointer to a static character string
+containing an error message.
+If a trace procedure returns an error, no further traces are
+invoked for the access and the traced access aborts with the
+given message.
+Trace procedures can use this facility to make variables
+read-only, for example (but note that the value of the variable
+will already have been modified before the trace procedure is
+called, so the trace procedure will have to restore the correct
+value).
+.PP
+The return value from \fIproc\fR is only used during read and
+write tracing.
+During unset traces, the return value is ignored and all relevant
+trace procedures will always be invoked.
+
+.SH "RESTRICTIONS"
+.PP
+A trace procedure can be called at any time, even when there
+is a partically-formed result in the interpreter's result area.  If
+the trace procedure does anything that could damage this result (such
+as calling \fBTcl_Eval\fR) then it must save the original values of
+the interpreter's \fBresult\fR and \fBfreeProc\fR fields and restore
+them before it returns.
+
+.SH "UNDEFINED VARIABLES"
+.PP
+It is legal to set a trace on an undefined variable.
+The variable will still appear to be undefined until the
+first time its value is set.
+If an undefined variable is traced and then unset, the unset will fail
+with an error (``no such variable''), but the trace
+procedure will still be invoked.
+
+.SH "TCL_TRACE_DELETED FLAG"
+.PP
+In an unset callback to \fIproc\fR, the TCL_TRACE_DELETED bit
+is set in \fIflags\fR if the trace is being removed as part
+of the deletion.
+Traces on a variable are always removed whenever the variable
+is deleted;  the only time TCL_TRACE_DELETED isn't set is for
+a whole-array trace invoked when only a single element of an
+array is unset.
+
+.SH "TCL_INTERP_DESTROYED"
+.PP
+When an interpreter is destroyed, unset traces are called for
+all of its variables.
+The TCL_INTERP_DESTROYED bit will be set in the \fIflags\fR
+argument passed to the trace procedures.
+Trace procedures must be extremely careful in what they do if
+the TCL_INTERP_DESTROYED bit is set.
+It is not safe for the procedures to invoke any Tcl procedures
+on the interpreter, since its state is partially deleted.
+All that trace procedures should do under these circumstances is
+to clean up and free their own internal data structures.
+
+.SH BUGS
+.PP
+Tcl doesn't do any error checking to prevent trace procedures
+from misusing the interpreter during traces with TCL_INTERP_DESTROYED
+set.

+\fBarray \fIoption arrayName\fR ?\fIarg arg ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command performs one of several operations on the
+variable given by \fIarrayName\fR.
+\fIArrayName\fR must be the name of an existing array variable.
+The \fIoption\fR argument determines what action is carried
+out by the command.
+The legal \fIoptions\fR (which may be abbreviated) are:
+.TP
+\fBarray anymore \fIarrayName searchId\fR
+Returns 1 if there are any more elements left to be processed
+in an array search, 0 if all elements have already been
+returned.
+\fISearchId\fR indicates which search on \fIarrayName\fR to
+check, and must have been the return value from a previous
+invocation of \fBarray startsearch\fR.
+This option is particularly useful if an array has an element
+with an empty name, since the return value from
+\fBarray nextelement\fR won't indicate whether the search
+has been completed.
+.TP
+\fBarray donesearch \fIarrayName searchId\fR
+This command terminates an array search and destroys all the
+state associated with that search.  \fISearchId\fR indicates
+which search on \fIarrayName\fR to destroy, and must have
+been the return value from a previous invocation of
+\fBarray startsearch\fR.  Returns an empty string.
+.TP
+\fBarray names \fIarrayName\fR
+Returns a list containing the names of all of the elements in
+the array.
+If there are no elements in the array then an empty string is
+returned.
+.TP
+\fBarray nextelement \fIarrayName searchId\fR
+Returns the name of the next element in \fIarrayName\fR, or
+an empty string if all elements of \fIarrayName\fR have
+already been returned in this search.  The \fIsearchId\fR
+argument identifies the search, and must have
+been the return value of an \fBarray startsearch\fR command.
+Warning:  if elements are added to or deleted from the array,
+then all searches are automatically terminated just as if
+\fBarray donesearch\fR had been invoked; this will cause
+\fBarray nextelement\fR operations to fail for those searches.
+.TP
+\fBarray size \fIarrayName\fR
+Returns a decimal string giving the number of elements in the
+array.
+.TP
+\fBarray startsearch \fIarrayName\fR
+This command initializes an element-by-element search through the
+array given by \fIarrayName\fR, such that invocations of the
+\fBarray nextelement\fR command will return the names of the
+individual elements in the array.
+When the search has been completed, the \fBarray donesearch\fR
+command should be invoked.
+The return value is a
+search identifier that must be used in \fBarray nextelement\fR
+and \fBarray donesearch\fR commands; it allows multiple
+searches to be underway simultaneously for the same array.

+\fBcase\fI string \fR?\fBin\fR? {\fIpatList body \fR?\fIpatList body \fR...?}
+.BE
+
+.SH DESCRIPTION
+.PP
+\fINote: the \fBcase\fI command is obsolete and is supported only
+for backward compatibility.  At some point in the future it may be
+removed entirely.  You should use the \fBswitch\fI command instead.\fR
+.PP
+The \fBcase\fR command matches \fIstring\fR against each of
+the \fIpatList\fR arguments in order.
+Each \fIpatList\fR argument is a list of one or
+more patterns.  If any of these patterns matches \fIstring\fR then
+\fBcase\fR evaluates the following \fIbody\fR argument
+by passing it recursively to the Tcl interpreter and returns the result
+of that evaluation.
+Each \fIpatList\fR argument consists of a single
+pattern or list of patterns.  Each pattern may contain any of the wild-cards
+described under \fBstring match\fR.  If a \fIpatList\fR
+argument is \fBdefault\fR, the corresponding body will be evaluated
+if no \fIpatList\fR matches \fIstring\fR.  If no \fIpatList\fR argument
+matches \fIstring\fR and no default is given, then the \fBcase\fR
+command returns an empty string.
+.PP
+Two syntaxes are provided for the \fIpatList\fR and \fIbody\fR arguments.
+The first uses a separate argument for each of the patterns and commands;
+this form is convenient if substitutions are desired on some of the
+patterns or commands.
+The second form places all of the patterns and commands together into
+a single argument; the argument must have proper list structure, with
+the elements of the list being the patterns and commands.
+The second form makes it easy to construct multi-line case commands,
+since the braces around the whole list make it unnecessary to include a
+backslash at the end of each line.
+Since the \fIpatList\fR arguments are in braces in the second form,
+no command or variable substitutions are performed on them;  this makes
+the behavior of the second form different than the first form in some
+cases.
+

+The \fBcatch\fR command may be used to prevent errors from aborting

+to execute \fIscript\fR, and always returns a TCL_OK code, regardless of
+any errors that might occur while executing \fIscript\fR.  The return
+value from \fBcatch\fR is a decimal string giving the
+code returned by the Tcl interpreter after executing \fIscript\fR.
+This will be \fB0\fR (TCL_OK) if there were no errors in \fIscript\fR;
+otherwise
+it will have a non-zero value corresponding to one of the exceptional
+return codes (see tcl.h for the definitions of code values).  If the
+\fIvarName\fR argument is given, then it gives the name of a variable;
+\fBcatch\fR will set the variable to the string returned
+from \fIscript\fR (either a result or an error message).

+.SH DESCRIPTION
+.PP
+Returns a TCL_ERROR code, which causes command interpretation to be
+unwound.  \fIMessage\fR is a string that is returned to the application
+to indicate what went wrong.
+.PP
+If the \fIinfo\fR argument is provided and is non-empty,
+it is used to initialize the global variable \fBerrorInfo\fR.
+\fBerrorInfo\fR is used to accumulate a stack trace of what
+was in progress when an error occurred; as nested commands unwind,
+the Tcl interpreter adds information to \fBerrorInfo\fR.  If the
+\fIinfo\fR argument is present, it is used to initialize
+\fBerrorInfo\fR and the first increment of unwind information
+will not be added by the Tcl interpreter.  In other
+words, the command containing the \fBerror\fR command will not appear
+in \fBerrorInfo\fR; in its place will be \fIinfo\fR.
+This feature is most useful in conjunction with the \fBcatch\fR command:
+if a caught error cannot be handled successfully, \fIinfo\fR can be used
+to return a stack trace reflecting the original point of occurrence
+of the error:
+.DS
+\fBcatch {...} errMsg
+set savedInfo $errorInfo
+\&...
+error $errMsg $savedInfo\fR
+.DE
+.PP
+If the \fIcode\fR argument is present, then its value is stored
+in the \fBerrorCode\fR global variable.  This variable is intended
+to hold a machine-readable description of the error in cases where
+such information is available; see the section BUILT-IN VARIABLES
+below for information on the proper format for the variable.
+If the \fIcode\fR argument is not
+present, then \fBerrorCode\fR is automatically reset to
+``NONE'' by the Tcl interpreter as part of processing the
+error generated by the command.

+expr \- Evalue an expression
+.SH SYNOPSIS
+\fBexpr \fIarg \fR?\fIarg arg ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+.VS
+Concatenates \fIarg\fR's (adding separator spaces between them),
+evaluates the result as a Tcl expression, and returns the value.
+.VE
+The operators permitted in Tcl expressions are a subset of
+the operators permitted in C expressions, and they have the
+same meaning and precedence as the corresponding C operators.
+Expressions almost always yield numeric results
+(integer or floating-point values).
+For example, the expression
+.DS
+\fBexpr 8.2 + 6\fR
+.DE
+evaluates to 14.2.
+Tcl expressions differ from C expressions in the way that
+operands are specified.  Also, Tcl expressions support
+non-numeric operands and string comparisons.
+.SH OPERANDS
+.PP
+A Tcl expression consists of a combination of operands, operators,
+and parentheses.
+White space may be used between the operands and operators and
+parentheses; it is ignored by the expression processor.
+Where possible, operands are interpreted as integer values.
+Integer values may be specified in decimal (the normal case), in octal (if the
+first character of the operand is \fB0\fR), or in hexadecimal (if the first
+two characters of the operand are \fB0x\fR).
+If an operand does not have one of the integer formats given
+above, then it is treated as a floating-point number if that is
+possible.  Floating-point numbers may be specified in any of the
+ways accepted by an ANSI-compliant C compiler (except that the
+``f'', ``F'', ``l'', and ``L'' suffixes will not be permitted in
+most installations).  For example, all of the
+following are valid floating-point numbers:  2.1, 3., 6e4, 7.91e+16.
+If no numeric interpretation is possible, then an operand is left
+as a string (and only a limited set of operators may be applied to
+it).
+.PP
+Operands may be specified in any of the following ways:
+.IP [1]
+As an numeric value, either integer or floating-point.
+.IP [2]
+As a Tcl variable, using standard \fB$\fR notation.
+The variable's value will be used as the operand.
+.IP [3]
+As a string enclosed in double-quotes.
+The expression parser will perform backslash, variable, and
+command substitutions on the information between the quotes,
+and use the resulting value as the operand
+.IP [4]
+As a string enclosed in braces.
+The characters between the open brace and matching close brace
+will be used as the operand without any substitutions.
+.IP [5]
+As a Tcl command enclosed in brackets.
+The command will be executed and its result will be used as
+the operand.
+.IP [6]
+.VS
+As a mathematical function whose arguments have any of the above
+forms for operands, such as ``\fBsin($x)\fR''.  See below for a list of defined
+functions.
+.VE
+.LP
+Where substitutions occur above (e.g. inside quoted strings), they
+are performed by the expression processor.
+However, an additional layer of substitution may already have
+been performed by the command parser before the expression
+processor was called.
+As discussed below, it is usually best to enclose expressions
+in braces to prevent the command parser from performing substitutions
+on the contents.
+.PP
+For some examples of simple expressions, suppose the variable
+\fBa\fR has the value 3 and
+the variable \fBb\fR has the value 6.
+Then the command on the left side of each of the lines below
+will produce the value on the right side of the line:
+.DS
+.ta 6c
+\fBexpr 3.1 + $a	6.1
+expr 2 + "$a.$b"	5.6
+expr 4*[llength "6 2"]	8
+expr {{word one} < "word $a"}	0\fR
+.DE
+.SH OPERATORS
+.PP
+The valid operators are listed below, grouped in decreasing order
+of precedence:
+.TP 20
+\fB\-\0\0~\0\0!\fR
+Unary minus, bit-wise NOT, logical NOT.  None of these operands
+may be applied to string operands, and bit-wise NOT may be
+applied only to integers.
+.TP 20
+\fB*\0\0/\0\0%\fR
+Multiply, divide, remainder.  None of these operands may be
+applied to string operands, and remainder may be applied only
+to integers.
+.VS
+The remainder will always have the same sign as the divisor and
+an absolute value smaller than the divisor.
+.VE
+.TP 20
+\fB+\0\0\-\fR
+Add and subtract.  Valid for any numeric operands.
+.TP 20
+\fB<<\0\0>>\fR
+Left and right shift.  Valid for integer operands only.
+.TP 20
+\fB<\0\0>\0\0<=\0\0>=\fR
+Boolean less, greater, less than or equal, and greater than or equal.
+Each operator produces 1 if the condition is true, 0 otherwise.
+These operators may be applied to strings as well as numeric operands,
+in which case string comparison is used.
+.TP 20
+\fB==\0\0!=\fR
+Boolean equal and not equal.  Each operator produces a zero/one result.
+Valid for all operand types.
+.TP 20
+\fB&\fR
+Bit-wise AND.  Valid for integer operands only.
+.TP 20
+\fB^\fR
+Bit-wise exclusive OR.  Valid for integer operands only.
+.TP 20
+\fB|\fR
+Bit-wise OR.  Valid for integer operands only.
+.TP 20
+\fB&&\fR
+Logical AND.  Produces a 1 result if both operands are non-zero, 0 otherwise.
+Valid for numeric operands only (integers or floating-point).
+.TP 20
+\fB||\fR
+Logical OR.  Produces a 0 result if both operands are zero, 1 otherwise.
+Valid for numeric operands only (integers or floating-point).
+.TP 20
+\fIx\fB?\fIy\fB:\fIz\fR
+If-then-else, as in C.  If \fIx\fR
+evaluates to non-zero, then the result is the value of \fIy\fR.
+Otherwise the result is the value of \fIz\fR.
+The \fIx\fR operand must have a numeric value.
+.LP
+See the C manual for more details on the results
+produced by each operator.
+All of the binary operators group left-to-right within the same
+precedence level.  For example, the command
+.DS
+\fBexpr 4*2 < 7\fR
+.DE
+returns 0.
+.PP
+The \fB&&\fP, \fB||\fP, and \fB?:\fP operators have ``lazy
+evaluation'', just as in C, 
+which means that operands are not evaluated if they are
+not needed to determine the outcome.  For example, in the command
+.DS
+\fBexpr {$v ? [a] : [b]}\fR
+.DE
+only one of \fB[a]\fR or \fB[b]\fR will actually be evaluated,
+depending on the value of \fB$v\fP.  Note, however, that this is
+only true if the entire expression is enclosed in braces;  otherwise
+the Tcl parser will evaluate both \fB[a]\fR and \fB[b]\fR before
+invoking the \fBexpr\fR command.
+.SH "MATH FUNCTIONS"
+.PP
+.VS
+Tcl supports the following mathematical functions in expressions:
+.DS
+.ta 3c 6c 9c
+\fBacos\fR	\fBcos\fR	\fBhypot\fR	\fBsinh\fR
+\fBasin\fR	\fBcosh\fR	\fBlog\fR	\fBsqrt\fR
+\fBatan\fR	\fBexp\fR	\fBlog10\fR	\fBtan\fR
+\fBatan2\fR	\fBfloor\fR	\fBpow\fR	\fBtanh\fR
+\fBceil\fR	\fBfmod\fR	\fBsin\fR
+.DE
+Each of these functions invokes the math library function of the same
+name;  see the manual entries for the library functions for details
+on what they do.  Tcl also implements the following functions for
+conversion between integers and floating-point numbers:
+.TP
+\fBabs(\fIarg\fB)\fI
+Returns the absolute value of \fIarg\fR.  \fIArg\fR may be either
+integer or floating-point, and the result is returned in the same form.
+.TP
+\fBdouble(\fIarg\fB)\fR
+If \fIarg\fR is a floating value, returns \fIarg\fR, otherwise converts
+\fIarg\fR to floating and returns the converted value.
+.TP
+\fBint(\fIarg\fB)\fR
+If \fIarg\fR is an integer value, returns \fIarg\fR, otherwise converts
+\fIarg\fR to integer by truncation and returns the converted value.
+.TP
+\fBround(\fIarg\fB)\fR
+If \fIarg\fR is an integer value, returns \fIarg\fR, otherwise converts
+\fIarg\fR to integer by rounding and returns the converted value.
+.PP
+In addition to these predifined functions, applications may
+define additional functions using \fBTcl_CreateMathFunc\fR().
+.VE
+.SH "TYPES, OVERFLOW, AND PRECISION"
+.PP
+All internal computations involving integers are done with the C type
+\fIlong\fP, and all internal computations involving floating-point are
+done with the C type \fIdouble\fP.
+When converting a string to floating-point, exponent overflow is
+detected and results in a Tcl error.
+For conversion to integer from string, detection of overflow depends
+on the behavior of some routines in the local C library, so it should
+be regarded as unreliable.
+In any case, integer overflow and underflow are generally not detected
+reliably for intermediate results.  Floating-point overflow and underflow
+are detected to the degree supported by the hardware, which is generally
+pretty reliable.
+.PP
+Conversion among internal representations for integer, floating-point,
+and string operands is done automatically as needed.
+For arithmetic computations, integers are used until some
+floating-point number is introduced, after which floating-point is used.
+For example,
+.DS
+\fBexpr 5 / 4\fR
+.DE
+returns 1, while
+.DS
+\fBexpr 5 / 4.0\fR
+\fBexpr 5 / ( [string length "abcd"] + 0.0 )
+.DE
+both return 1.25.
+.VS
+Floating-point values are always returned with a ``.''
+or an ``e'' so that they will not look like integer values.  For
+example,
+.DS
+\fBexpr 20.0/5.0\fR
+.DE
+returns ``4.0'', not ``4''.  The global variable \fBtcl_precision\fR
+determines the the number of significant digits that are retained
+when floating values are converted to strings (except that trailing
+zeroes are omitted).  If \fBtcl_precision\fR
+is unset then 6 digits of precision are used.
+To retain all of the significant bits of an IEEE floating-point
+number set \fBtcl_precision\fR to 17;  if a value is converted to
+string with 17 digits of precision and then converted back to binary
+for some later calculation, the resulting binary value is guaranteed
+to be identical to the original one.
+.VE
+
+.SH "STRING OPERATIONS"
+.PP
+String values may be used as operands of the comparison operators,
+although the expression evaluator tries to do comparisons as integer
+or floating-point when it can.
+If one of the operands of a comparison is a string and the other
+has a numeric value, the numeric operand is converted back to
+a string using the C \fIsprintf\fP format specifier
+\fB%d\fR for integers and \fB%g\fR for floating-point values.
+For example, the commands
+.DS
+\fBexpr {"0x03" > "2"}\fR
+\fBexpr {"0y" < "0x12"}\fR
+.DE
+both return 1.  The first comparison is done using integer
+comparison, and the second is done using string comparison after
+the second operand is converted to the string ``18''.

+.SH SYNOPSIS
+\fBfile \fIoption\fR \fIname\fR ?\fIarg arg ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command provides several operations on a file's name or attributes.
+\fIName\fR is the name of a file;
+if it starts with a tilde, then tilde substitution is done before
+executing the command (see the manual entry for \fBTcl_TildeSubst\fR
+for details).
+\fIOption\fR indicates what to do with the file name.  Any unique
+abbreviation for \fIoption\fR is acceptable.  The valid options are:
+.TP
+\fBfile \fBatime \fIname\fR
+Returns a decimal string giving the time at which file \fIname\fR
+was last accessed.  The time is measured in the standard POSIX
+fashion as seconds from a fixed starting time (often January 1, 1970).
+If the file doesn't exist or its access time cannot be queried then an
+error is generated.
+.TP
+\fBfile \fBdirname \fIname\fR
+Returns all of the characters in \fIname\fR up to but not including
+the last slash character.  If there are no slashes in \fIname\fR
+then returns ``.''.  If the last slash in \fIname\fR is its first
+character, then return ``/''.
+.TP
+\fBfile \fBexecutable \fIname\fR
+Returns \fB1\fR if file \fIname\fR is executable by
+the current user, \fB0\fR otherwise.
+.TP
+\fBfile \fBexists \fIname\fR
+Returns \fB1\fR if file \fIname\fR exists and the current user has
+search privileges for the directories leading to it, \fB0\fR otherwise.
+.TP
+\fBfile \fBextension \fIname\fR
+Returns all of the characters in \fIname\fR after and including the
+last dot in \fIname\fR.  If there is no dot in \fIname\fR then returns
+the empty string.
+.TP
+\fBfile \fBisdirectory \fIname\fR
+Returns \fB1\fR if file \fIname\fR is a directory,
+\fB0\fR otherwise.
+.TP
+\fBfile \fBisfile \fIname\fR
+Returns \fB1\fR if file \fIname\fR is a regular file,
+\fB0\fR otherwise.
+.TP
+\fBfile lstat \fIname varName\fR
+Same as \fBstat\fR option (see below) except uses the \fIlstat\fR
+kernel call instead of \fIstat\fR.  This means that if \fIname\fR
+refers to a symbolic link the information returned in \fIvarName\fR
+is for the link rather than the file it refers to.  On systems that
+don't support symbolic links this option behaves exactly the same
+as the \fBstat\fR option.
+.TP
+\fBfile \fBmtime \fIname\fR
+Returns a decimal string giving the time at which file \fIname\fR
+was last modified.  The time is measured in the standard POSIX
+fashion as seconds from a fixed starting time (often January 1, 1970).
+If the file doesn't exist or its modified time cannot be queried then an
+error is generated.
+.TP
+\fBfile \fBowned \fIname\fR
+Returns \fB1\fR if file \fIname\fR is owned by the current user,
+\fB0\fR otherwise.
+.TP
+\fBfile \fBreadable \fIname\fR
+Returns \fB1\fR if file \fIname\fR is readable by
+the current user, \fB0\fR otherwise.
+.TP
+\fBfile readlink \fIname\fR
+Returns the value of the symbolic link given by \fIname\fR (i.e. the
+name of the file it points to).  If
+\fIname\fR isn't a symbolic link or its value cannot be read, then
+an error is returned.  On systems that don't support symbolic links
+this option is undefined.
+.TP
+\fBfile \fBrootname \fIname\fR
+Returns all of the characters in \fIname\fR up to but not including
+the last ``.'' character in the name.  If \fIname\fR doesn't contain
+a dot, then returns \fIname\fR.
+.TP
+\fBfile \fBsize \fIname\fR
+Returns a decimal string giving the size of file \fIname\fR in bytes.
+If the file doesn't exist or its size cannot be queried then an
+error is generated.
+.TP
+\fBfile \fBstat  \fIname varName\fR
+Invokes the \fBstat\fR kernel call on \fIname\fR, and uses the
+variable given by \fIvarName\fR to hold information returned from
+the kernel call.
+\fIVarName\fR is treated as an array variable,
+and the following elements of that variable are set: \fBatime\fR,
+\fBctime\fR, \fBdev\fR, \fBgid\fR, \fBino\fR, \fBmode\fR, \fBmtime\fR,
+\fBnlink\fR, \fBsize\fR, \fBtype\fR, \fBuid\fR.
+Each element except \fBtype\fR is a decimal string with the value of

+for \- ``For'' loop
+.SH SYNOPSIS
+\fBfor \fIstart test next body\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+\fBFor\fR is a looping command, similar in structure to the C
+\fBfor\fR statement.  The \fIstart\fR, \fInext\fR, and
+\fIbody\fR arguments must be Tcl command strings, and \fItest\fR
+is an expression string.
+The \fBfor\fR command first invokes the Tcl interpreter to
+execute \fIstart\fR.  Then it repeatedly evaluates \fItest\fR as
+an expression; if the result is non-zero it invokes the Tcl
+interpreter on \fIbody\fR, then invokes the Tcl interpreter on \fInext\fR,
+then repeats the loop.  The command terminates when \fItest\fR evaluates
+to 0.  If a \fBcontinue\fR command is invoked within \fIbody\fR then
+any remaining commands in the current execution of \fIbody\fR are skipped;
+processing continues by invoking the Tcl interpreter on \fInext\fR, then
+evaluating \fItest\fR, and so on.  If a \fBbreak\fR command is invoked
+within \fIbody\fR
+or \fInext\fR,
+then the \fBfor\fR command will
+return immediately.
+The operation of \fBbreak\fR and \fBcontinue\fR are similar to the
+corresponding statements in C.
+\fBFor\fR returns an empty string.

+.SH NAME
+format \- Format a string in the style of sprintf
+.SH SYNOPSIS
+\fBformat \fIformatString \fR?\fIarg arg ...\fR?
+.BE
+
+.SH INTRODUCTION
+.PP
+This command generates a formatted string in the same way as the
+ANSI C \fBsprintf\fR procedure (it uses \fBsprintf\fR in its
+implementation).
+\fIFormatString\fR indicates how to format the result, using
+\fB%\fR conversion specifiers as in \fBsprintf\fR, and the additional
+arguments, if any, provide values to be substituted into the result.
+The return value from \fBformat\fR is the formatted string.
+
+.SH "DETAILS ON FORMATTING"
+.PP
+The command operates by scanning \fIformatString\fR from left to right. 
+Each character from the format string is appended to the result
+string unless it is a percent sign.
+If the character is a \fB%\fR then it is not copied to the result string.
+Instead, the characters following the \fB%\fR character are treated as
+a conversion specifier.
+The conversion specifier controls the conversion of the next successive
+\fIarg\fR to a particular format and the result is appended to 
+the result string in place of the conversion specifier.
+If there are multiple conversion specifiers in the format string,
+then each one controls the conversion of one additional \fIarg\fR.
+The \fBformat\fR command must be given enough \fIarg\fRs to meet the needs
+of all of the conversion specifiers in \fIformatString\fR.
+.PP
+Each conversion specifier may contain up to six different parts:
+.VS
+an XPG3 position specifier,
+.VE
+a set of flags, a minimum field width, a precision, a length modifier,
+and a conversion character.
+Any of these fields may be omitted except for the conversion character.
+The fields that are present must appear in the order given above.
+The paragraphs below discuss each of these fields in turn.
+.PP
+.VS
+If the \fB%\fR is followed by a decimal number and a \fB$\fR, as in
+``\fB%2$d\fR'', then the value to convert is not taken from the
+next sequential argument.
+Instead, it is taken from the argument indicated by the number,
+where 1 corresponds to the first \fIarg\fR.
+If the conversion specifier requires multiple arguments because
+of \fB*\fR characters in the specifier then
+successive arguments are used, starting with the argument
+given by the number.
+This follows the XPG3 conventions for positional specifiers.
+If there are any positional specifiers in \fIformatString\fR
+then all of the specifiers must be positional.
+.VE
+.PP
+The second portion of a conversion specifier may contain any of the
+following flag characters, in any order:
+.TP 10
+\fB\-\fR
+Specifies that the converted argument should be left-justified 
+in its field (numbers are normally right-justified with leading 
+spaces if needed).
+.TP 10
+\fB+\fR
+Specifies that a number should always be printed with a sign, 
+even if positive.
+.TP 10
+\fIspace\fR
+Specifies that a space should be added to the beginning of the 
+number if the first character isn't a sign.
+.TP 10
+\fB0\fR
+Specifies that the number should be padded on the left with 
+zeroes instead of spaces.
+.TP 10
+\fB#\fR
+Requests an alternate output form. For \fBo\fR and \fBO\fR
+conversions it guarantees that the first digit is always \fB0\fR.
+For \fBx\fR or \fBX\fR conversions, \fB0x\fR or \fB0X\fR (respectively)
+will be added to the beginning of the result unless it is zero.
+For all floating-point conversions (\fBe\fR, \fBE\fR, \fBf\fR,
+\fBg\fR, and \fBG\fR) it guarantees that the result always 
+has a decimal point.
+For \fBg\fR and \fBG\fR conversions it specifies that 
+trailing zeroes should not be removed.
+.PP
+The third portion of a conversion specifier is a number giving a
+minimum field width for this conversion.
+It is typically used to make columns line up in tabular printouts.
+If the converted argument contains fewer characters than the
+minimum field width then it will be padded so that it is as wide
+as the minimum field width.
+Padding normally occurs by adding extra spaces on the left of the
+converted argument, but the \fB0\fR and \fB\-\fR flags 
+may be used to specify padding with zeroes on the left or with
+spaces on the right, respectively.
+If the minimum field width is specified as \fB*\fR rather than
+a number, then the next argument to the \fBformat\fR command
+determines the minimum field width; it must be a numeric string.
+.PP
+The fourth portion of a conversion specifier is a precision,
+which consists of a period followed by a number.
+The number is used in different ways for different conversions.
+For \fBe\fR, \fBE\fR, and \fBf\fR conversions it specifies the number
+of digits to appear to the right of the decimal point.
+For \fBg\fR and \fBG\fR conversions it specifies the total number
+of digits to appear, including those on both sides of the decimal
+point (however, trailing zeroes after the decimal point will still
+be omitted unless the \fB#\fR flag has been specified).
+For integer conversions, it specifies a mimimum number of digits
+to print (leading zeroes will be added if necessary).
+For \fBs\fR conversions it specifies the maximum number of characters to be 
+printed; if the string is longer than this then the trailing characters will be dropped.
+If the precision is specified with \fB*\fR rather than a number
+then the next argument to the \fBformat\fR command determines the precision;
+it must be a numeric string.
+.PP
+The fourth part of a conversion specifier is a length modifier,
+which must be \fBh\fR or \fBl\fR.
+If it is \fBh\fR it specifies that the numeric value should be
+truncated to a 16-bit value before converting.
+This option is rarely useful.
+The \fBl\fR modifier is ignored.
+.PP
+The last thing in a conversion specifier is an alphabetic character
+that determines what kind of conversion to perform.
+The following conversion characters are currently supported:
+.TP 10
+\fBd\fR
+Convert integer to signed decimal string.
+.TP 10
+\fBu\fR
+Convert integer to unsigned decimal string.
+.TP 10
+\fBi\fR
+Convert integer to signed decimal string;  the integer may either be
+in decimal, in octal (with a leading \fB0\fR) or in hexadecimal
+(with a leading \fB0x\fR).
+.TP 10
+\fBo\fR
+Convert integer to unsigned octal string.
+.TP 10
+\fBx\fR or \fBX\fR
+Convert integer to unsigned hexadecimal string, using digits
+``0123456789abcdef'' for \fBx\fR and ``0123456789ABCDEF'' for \fBX\fR).
+.TP 10
+\fBc\fR
+Convert integer to the 8-bit character it represents.
+.TP 10
+\fBs\fR
+No conversion; just insert string.
+.TP 10
+\fBf\fR
+Convert floating-point number to signed decimal string of 
+the form \fIxx.yyy\fR, where the number of \fIy\fR's is determined by 
+the precision (default: 6).
+If the precision is 0 then no decimal point is output.
+.TP 10
+\fBe\fR or \fBe\fR
+Convert floating-point number to scientific notation in the 
+form \fIx.yyy\fBe\(+-\fIzz\fR, where the number of \fIy\fR's is determined 
+by the precision (default: 6).
+If the precision is 0 then no decimal point is output.
+If the \fBE\fR form is used then \fBE\fR is 
+printed instead of \fBe\fR.
+.TP 10
+\fBg\fR or \fBG\fR
+If the exponent is less than \-4 or greater than or equal to the 
+precision, then convert floating-point number as for \fB%e\fR or 
+\fB%E\fR.
+Otherwise convert as for \fB%f\fR.
+Trailing zeroes and a trailing decimal point are omitted.
+.TP 10
+\fB%\fR
+No conversion: just insert \fB%\fR.
+.LP
+For the numerical conversions the argument being converted must
+be an integer or floating-point string; format converts the argument
+to binary and then converts it back to a string according to 
+the conversion specifier.
+
+.SH "DIFFERENCES FROM ANSI SPRINTF"
+.PP
+.VS
+The behavior of the format command is the same as the
+ANSI C \fBsprintf\fR procedure except for the following
+differences:
+.IP [1]
+\fB%p\fR and \fB%n\fR specifiers are not currently supported.
+.VE
+.IP [2]
+For \fB%c\fR conversions the argument must be a decimal string,
+which will then be converted to the corresponding character value.
+.IP [3]
+.VS
+The \fBl\fR modifier is ignored;  integer values are always converted
+as if there were no modifier present and real values are always
+converted as if the \fBl\fR modifier were present (i.e. type
+\fBdouble\fR is used for the internal representation).
+If the \fBh\fR modifier is specified then integer values are truncated
+to \fBshort\fR before conversion.

+.SH SYNOPSIS
+\fBglob \fR?\fIswitches\fR? \fIpattern \fR?\fIpattern ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command performs file name ``globbing'' in a fashion similar to
+the csh shell.  It returns a list of the files whose names match any
+of the \fIpattern\fR arguments.
+.LP
+If the initial arguments to \fBglob\fR start with \fB\-\fR then
+.VS
+they are treated as switches.  The following switches are
+currently supported:
+.TP 15
+\fB\-nocomplain\fR
+Allows an empty list to be returned without error;  without this
+switch an error is returned if the result list would be empty.
+.TP 15
+\fB\-\|\-\fR
+Marks the end of switches.  The argument following this one will
+be treated as a \fIpattern\fR even if it starts with a \fB\-.
+.VE
+.PP
+The \fIpattern\fR arguments may contain any of the following
+special characters:
+.TP 10
+\fB?\fR
+Matches any single character.
+.TP 10
+\fB*\fR
+Matches any sequence of zero or more characters.
+.TP 10
+\fB[\fIchars\fB]\fR
+Matches any single character in \fIchars\fR.  If \fIchars\fR
+contains a sequence of the form \fIa\fB\-\fIb\fR then any
+character between \fIa\fR and \fIb\fR (inclusive) will match.
+.TP 10
+\fB\e\fIx\fR
+Matches the character \fIx\fR.
+.TP 10
+\fB{\fIa\fB,\fIb\fB,\fI...\fR}
+Matches any of the strings \fIa\fR, \fIb\fR, etc.
+.LP
+As with csh, a  ``.'' at the beginning of a file's name or just
+after a ``/'' must be matched explicitly or with a {} construct.
+In addition, all ``/'' characters must be matched explicitly.
+.LP
+If the first character in a \fIpattern\fR is ``~'' then it refers
+to the home directory for the user whose name follows the ``~''.
+If the ``~'' is followed immediately by ``/'' then the value of
+the HOME environment variable is used.
+.LP
+The \fBglob\fR command differs from csh globbing in two ways.
+First, it does not sort its result list (use the \fBlsort\fR
+command if you want the list sorted).
+.VS
+Second, \fBglob\fR only returns the names of files that actually
+exist;  in csh no check for existence is made unless a pattern
+contains a ?, *, or [] construct.
+.VE
+

+.SH NAME
+history \- Manipulate the history list
+.SH SYNOPSIS
+\fBhistory \fR?\fIoption\fR? ?\fIarg arg ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+The \fBhistory\fR command performs one of several operations related to
+recently-executed commands recorded in a history list.  Each of
+these recorded commands is referred to as an ``event''.  When
+specifying an event to the \fBhistory\fR command, the following
+forms may be used:
+.IP [1]
+A number:  if positive, it refers to the event with
+that number (all events are numbered starting at 1).  If the number
+is negative, it selects an event relative to the current event
+(\fB\-1\fR refers to the previous event, \fB\-2\fR to the one before that, and
+so on).
+.IP [2]
+A string:  selects the most recent event that matches the string.
+An event is considered to match the string either if the string is
+the same as the first characters of the event, or if the string
+matches the event in the sense of the \fBstring match\fR command.
+.LP
+The \fBhistory\fR command can take any of the following forms:
+.TP
+\fBhistory\fR
+Same
+as \fBhistory info\fR, described below.
+.TP
+\fBhistory add\fI command \fR?\fBexec\fR?
+Adds the \fIcommand\fR argument to the history list as a new event.  If
+\fBexec\fR is specified (or abbreviated) then the command is also
+executed and its result is returned.  If \fBexec\fR isn't specified
+then an empty string is returned as result.
+.TP
+\fBhistory change\fI newValue\fR ?\fIevent\fR?
+Replaces the value recorded for an event with \fInewValue\fR.  \fIEvent\fR
+specifies the event to replace, and
+defaults to the \fIcurrent\fR event (not event \fB\-1\fR).  This command
+is intended for use in commands that implement new forms of history
+substitution and wish to replace the current event (which invokes the
+substitution) with the command created through substitution.  The return
+value is an empty string.
+.TP
+\fBhistory event\fR ?\fIevent\fR?
+Returns the value of the event given by \fIevent\fR.  \fIEvent\fR
+defaults to \fB\-1\fR.  This command causes history revision to occur:
+see below for details.
+.TP
+\fBhistory info \fR?\fIcount\fR?
+Returns a formatted string (intended for humans to read) giving
+the event number and contents for each of the events in the history
+list except the current event.  If \fIcount\fR is specified
+then only the most recent \fIcount\fR events are returned.
+.TP
+\fBhistory keep \fIcount\fR
+This command may be used to change the size of the history list to
+\fIcount\fR events.  Initially, 20 events are retained in the history
+list.  This command returns an empty string.
+.TP
+\fBhistory nextid\fR
+Returns the number of the next event to be recorded
+in the history list.  It is useful for things like printing the
+event number in command-line prompts.
+.TP
+\fBhistory redo \fR?\fIevent\fR?
+Re-executes the command indicated by \fIevent\fR and return its result.
+\fIEvent\fR defaults to \fB\-1\fR.  This command results in history
+revision:  see below for details.
+.TP
+\fBhistory substitute \fIold new \fR?\fIevent\fR?
+Retrieves the command given by \fIevent\fR
+(\fB\-1\fR by default), replace any occurrences of \fIold\fR by
+\fInew\fR in the command (only simple character equality is supported;
+no wild cards), execute the resulting command, and return the result
+of that execution.  This command results in history
+revision:  see below for details.
+.TP
+\fBhistory words \fIselector\fR ?\fIevent\fR?
+Retrieves from the command given by \fIevent\fR (\fB\-1\fR by default)
+the words given by \fIselector\fR, and return those words in a string
+separated by spaces.  The \fBselector\fR argument has three forms.
+If it is a single number then it selects the word given by that
+number (\fB0\fR for the command name, \fB1\fR for its first argument,
+and so on).  If it consists of two numbers separated by a dash,
+then it selects all the arguments between those two.  Otherwise
+\fBselector\fR is treated as a pattern; all words matching that
+pattern (in the sense of \fBstring match\fR) are returned.  In
+the numeric forms \fB$\fR may be used
+to select the last word of a command.
+For example, suppose the most recent command in the history list is
+.RS
+.DS
+\fBformat  {%s is %d years old} Alice [expr $ageInMonths/12]\fR
+.DE
+Below are some history commands and the results they would produce:
+.DS
+.ta 4c
+.fi
+.UL Command "	"
+.UL Result
+.nf
+
+\fBhistory words $	[expr $ageInMonths/12]\fR
+\fBhistory words 1-2	{%s is %d years  old} Alice\fR
+\fBhistory words *a*o*	{%s is %d years old} [expr $ageInMonths/12]\fR
+.DE
+\fBHistory words\fR results in history revision:  see below for details.
+.RE
+.SH "HISTORY REVISION"
+.PP
+The history options \fBevent\fR, \fBredo\fR, \fBsubstitute\fR,
+and \fBwords\fR result in ``history revision''.
+When one of these options is invoked then the current event
+is modified to eliminate the history command and replace it with
+the result of the history command.
+For example, suppose that the most recent command in the history
+list is
+.DS
+\fBset a [expr $b+2]\fR
+.DE
+and suppose that the next command invoked is one of the ones on
+the left side of the table below.  The command actually recorded in
+the history event will be the corresponding one on the right side
+of the table.
+.ne 1.5c
+.DS
+.ta 4c
+.fi
+.UL "Command Typed" "	"
+.UL "Command Recorded"
+.nf
+
+\fBhistory redo	set a [expr $b+2]\fR
+\fBhistory s a b	set b [expr $b+2]\fR
+\fBset c [history w 2]	set c [expr $b+2]\fR
+.DE
+History revision is needed because event specifiers like \fB\-1\fR
+are only valid at a particular time:  once more events have been
+added to the history list a different event specifier would be
+needed.
+History revision occurs even when \fBhistory\fR is invoked
+indirectly from the current event (e.g. a user types a command
+that invokes a Tcl procedure that invokes \fBhistory\fR):  the
+top-level command whose execution eventually resulted in a
+\fBhistory\fR command is replaced.
+If you wish to invoke commands like \fBhistory words\fR without
+history revision, you can use \fBhistory event\fR to save the
+current history event and then use \fBhistory change\fR to
+restore it later.

+.BE
+
+.SH DESCRIPTION
+.PP
+The \fIif\fR command evaluates \fIexpr1\fR as an expression (in the
+same way that \fBexpr\fR evaluates its argument).  The value of the
+expression must be a boolean
+.VS
+(a numeric value, where 0 is false and
+anything is true, or a string value such as \fBtrue\fR or \fByes\fR
+for true and \fBfalse\fR or \fBno\fR for false);
+.VE
+if it is true then \fIbody1\fR is executed by passing it to the
+Tcl interpreter.
+Otherwise \fIexpr2\fR is evaluated as an expression and if it is true
+then \fBbody2\fR is executed, and so on.
+If none of the expressions evaluates to true then \fIbodyN\fR is
+executed.
+The \fBthen\fR and \fBelse\fR arguments are optional
+``noise words'' to make the command easier to read.
+There may be any number of \fBelseif\fR clauses, including zero.
+\fIBodyN\fR may also be omitted as long as \fBelse\fR is omitted too.
+The return value from the command is the result of the body script
+that was executed, or an empty string
+if none of the expressions was non-zero and there was no \fIbodyN\fR.

+.SH SYNOPSIS
+\fBinfo \fIoption \fR?\fIarg arg ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command provides information about various internals of the Tcl
+interpreter.
+The legal \fIoption\fR's (which may be abbreviated) are:
+.TP
+\fBinfo args \fIprocname\fR
+Returns a list containing the names of the arguments to procedure
+\fIprocname\fR, in order.  \fIProcname\fR must be the name of a
+Tcl command procedure.
+.TP
+\fBinfo body \fIprocname\fR
+Returns the body of procedure \fIprocname\fR.  \fIProcname\fR must be
+the name of a Tcl command procedure.
+.TP
+\fBinfo cmdcount\fR
+Returns a count of the total number of commands that have been invoked
+in this interpreter.
+.TP
+\fBinfo commands \fR?\fIpattern\fR?
+If \fIpattern\fR isn't specified, returns a list of names of all the
+Tcl commands, including both the built-in commands written in C and
+the command procedures defined using the \fBproc\fR command.
+If \fIpattern\fR is specified, only those names matching \fIpattern\fR
+are returned.  Matching is determined using the same rules as for
+\fBstring match\fR.
+.TP
+\fBinfo complete \fIcommand\fR
+Returns 1 if \fIcommand\fR is a complete Tcl command in the sense of
+having no unclosed quotes, braces, brackets or array element names,
+If the command doesn't appear to be complete then 0 is returned.
+This command is typically used in line-oriented input environments
+to allow users to type in commands that span multiple lines;  if the
+command isn't complete, the script can delay evaluating it until additional
+lines have been typed to complete the command.
+.TP
+\fBinfo default \fIprocname arg varname\fR
+\fIProcname\fR must be the name of a Tcl command procedure and \fIarg\fR
+must be the name of an argument to that procedure.  If \fIarg\fR
+doesn't have a default value then the command returns \fB0\fR.
+Otherwise it returns \fB1\fR and places the default value of \fIarg\fR
+into variable \fIvarname\fR.
+.TP
+\fBinfo exists \fIvarName\fR
+Returns \fB1\fR if the variable named \fIvarName\fR exists in the
+current context (either as a global or local variable), returns \fB0\fR
+otherwise.
+.TP
+\fBinfo globals \fR?\fIpattern\fR?
+If \fIpattern\fR isn't specified, returns a list of all the names
+of currently-defined global variables.
+If \fIpattern\fR is specified, only those names matching \fIpattern\fR
+are returned.  Matching is determined using the same rules as for
+\fBstring match\fR.
+.TP
+\fBinfo level\fR ?\fInumber\fR?
+If \fInumber\fR is not specified, this command returns a number
+giving the stack level of the invoking procedure, or 0 if the
+command is invoked at top-level.  If \fInumber\fR is specified,
+then the result is a list consisting of the name and arguments for the
+procedure call at level \fInumber\fR on the stack.  If \fInumber\fR
+is positive then it selects a particular stack level (1 refers
+to the top-most active procedure, 2 to the procedure it called, and
+so on); otherwise it gives a level relative to the current level
+(0 refers to the current procedure, -1 to its caller, and so on).
+See the \fBuplevel\fR command for more information on what stack
+levels mean.
+.TP
+\fBinfo library\fR
+Returns the name of the library directory in which standard Tcl
+scripts are stored.
+The default value for the library is compiled into Tcl, but it
+may be overridden by setting the TCL_LIBRARY environment variable.
+If there is no TCL_LIBRARY variable and no compiled-in value then
+and error is generated.
+See the \fBlibrary\fR manual entry for details of the facilities
+provided by the Tcl script library.
+Normally each application will have its own application-specific
+script library in addition to the Tcl script library;  I suggest that
+each application set a global variable with a name like
+\fB$\fIapp\fB_library\fR (where \fIapp\fR is the application's name)
+to hold the location of that application's library directory.
+.TP
+\fBinfo locals \fR?\fIpattern\fR?
+If \fIpattern\fR isn't specified, returns a list of all the names
+of currently-defined local variables, including arguments to the
+current procedure, if any.
+Variables defined with the \fBglobal\fR and \fBupvar\fR commands
+will not be returned.
+If \fIpattern\fR is specified, only those names matching \fIpattern\fR
+are returned.  Matching is determined using the same rules as for
+\fBstring match\fR.
+.TP
+\fBinfo patchlevel\fR
+.VS
+Returns a decimal integer giving the current patch level for Tcl.
+The patch level is incremented for each new release or patch, and
+it uniquely identifies an official version of Tcl.
+.VE
+.TP
+\fBinfo procs \fR?\fIpattern\fR?
+If \fIpattern\fR isn't specified, returns a list of all the
+names of Tcl command procedures.
+If \fIpattern\fR is specified, only those names matching \fIpattern\fR
+are returned.  Matching is determined using the same rules as for
+\fBstring match\fR.
+.TP
+\fBinfo script\fR
+If a Tcl script file is currently being evaluated (i.e. there is a
+call to \fBTcl_EvalFile\fR active or there is an active invocation
+of the \fBsource\fR command), then this command returns the name
+of the innermost file being processed.  Otherwise the command returns an
+empty string.
+.TP
+\fBinfo tclversion\fR
+Returns the version number for this version of Tcl in the form \fIx.y\fR,
+where changes to \fIx\fR represent major changes with probable
+incompatibilities and changes to \fIy\fR represent small enhancements and
+bug fixes that retain backward compatibility.
+.TP
+\fBinfo vars\fR ?\fIpattern\fR?
+If \fIpattern\fR isn't specified,
+returns a list of all the names of currently-visible variables, including
+both locals and currently-visible globals.
+If \fIpattern\fR is specified, only those names matching \fIpattern\fR
+are returned.  Matching is determined using the same rules as for
+\fBstring match\fR.

+This command treats the variable given by \fIvarName\fR as a list
+and appends each of the \fIvalue\fR arguments to that list as a separate
+element, with spaces between elements.
+If \fIvarName\fR doesn't exist, it is created as a list with elements
+given by the \fIvalue\fR arguments.
+\fBLappend\fR is similar to \fBappend\fR except that the \fIvalue\fRs
+are appended as list elements rather than raw text.
+This command provides a relatively efficient way to build up
+large lists.  For example, ``\fBlappend a $b\fR'' is much
+more efficient than ``\fBset a [concat $a [list $b]]\fR'' when
+\fB$a\fR is long.
+

+
+.SH INTRODUCTION
+.PP
+Tcl includes a library of Tcl procedures for commonly-needed functions.
+The procedures defined in the Tcl library are generic ones suitable
+for use by many different applications.
+The location of the Tcl library is returned by the \fBinfo library\fR
+command.
+In addition to the Tcl library, each application will normally have
+its own library of support procedures as well;  the location of this
+library is normally given by the value of the \fB$\fIapp\fB_library\fR
+global variable, where \fIapp\fR is the name of the application.
+For example, the location of the Tk library is kept in the variable
+\fB$tk_library\fR.
+.PP
+To access the procedures in the Tcl library, an application should
+source the file \fBinit.tcl\fR in the library, for example with
+the Tcl command
+.DS
+\fBsource [info library]/init.tcl
+.DE
+This will define the \fBunknown\fR procedure and arrange for the
+other procedures to be loaded on-demand using the auto-load
+mechanism defined below.
+
+.SH "COMMAND PROCEDURES"
+.PP
+The following procedures are provided in the Tcl library:
+.TP
+\fBauto_execok \fIcmd\fR
+Determines whether there is an executable file by the name \fIcmd\fR.
+This command examines the directories in the current search path
+(given by the PATH enviornment variable) to see if there is an
+executable file named \fIcmd\fR in any of those directories.
+If so, it returns 1;  if not it returns 0.  \fBAuto_exec\fR
+remembers information about previous searches in an array
+named \fBauto_execs\fR;  this avoids the path search in
+future calls for the same \fIcmd\fR.  The command \fBauto_reset\fR
+may be used to force \fBauto_execok\fR to forget its cached
+information.
+.TP
+\fBauto_load \fIcmd\fR
+This command attempts to load the definition for a Tcl command named
+\fIcmd\fR.
+To do this, it searches an \fIauto-load path\fR, which is a list of
+one or more directories.
+The auto-load path is given by the global variable \fB$auto_path\fR
+if it exists.
+If there is no \fB$auto_path\fR variable, then the TCLLIBPATH environment
+variable is used, if it exists.
+Otherwise the auto-load path consists of just the Tcl library directory.
+Within each directory in the auto-load path there must be a file
+\fBtclIndex\fR that describes one
+.VS
+or more commands defined in that directory
+and a script to evaluate to load each of the commands.
+The \fBtclIndex\fR file should be generated with the
+\fBauto_mkindex\fR command.
+If \fIcmd\fR is found in an index file, then the appropriate
+script is evaluated to create the command.
+.VE
+The \fBauto_load\fR command returns 1 if \fIcmd\fR was successfully
+created.
+The command returns 0 if there was no index entry for \fIcmd\fR
+or if the script didn't actually define \fIcmd\fR (e.g. because
+index information is out of date).
+If an error occurs while processing the script, then that error
+is returned.
+\fBAuto_load\fR only reads the index information once and saves it
+in the array \fBauto_index\fR;  future calls to \fBauto_load\fR
+check for \fIcmd\fR in the array rather than re-reading the index
+files.
+The cached index information may be deleted with the command
+\fBauto_reset\fR.
+This will force the next \fBauto_load\fR command to reload the
+index database from disk.
+.TP
+\fBauto_mkindex \fIdir pattern pattern ...\fR
+.VS
+Generates an index suitable for use by \fBauto_load\fR.
+The command searches \fIdir\fR for all files whose names match
+any of the \fIpattern\fR arguments
+.VE
+(matching is done with the \fBglob\fR command),
+generates an index of all the Tcl command
+procedures defined in all the matching files, and stores the
+index information in a file named \fBtclIndex\fR in \fIdir\fR.
+For example, the command
+.RS
+.DS
+\fBauto_mkindex foo *.tcl\fR
+.DE
+.LP
+will read all the \fB.tcl\fR files in subdirectory \fBfoo\fR
+and generate a new index file \fBfoo/tclIndex\fR.
+.PP
+\fBAuto_mkindex\fR parses the Tcl scripts in a relatively
+unsophisticated way:  if any line contains the word \fBproc\fR
+as its first characters then it is assumed to be a procedure
+definition and the next word of the line is taken as the
+procedure's name.
+Procedure definitions that don't appear in this way (e.g. they
+have spaces before the \fBproc\fR) will not be indexed.
+.RE
+.TP
+\fBauto_reset\fR
+Destroys all the information cached by \fBauto_execok\fR and
+\fBauto_load\fR.
+This information will be re-read from disk the next time it is
+needed.
+\fBAuto_reset\fR also deletes any procedures listed in the auto-load
+index, so that fresh copies of them will be loaded the next time
+that they're used.
+.TP
+\fBparray \fIarrayName\fR
+Prints on standard output the names and values of all the elements
+in the array \fIarrayName\fR.
+\fBArrayName\fR must be an array accessible to the caller of \fBparray\fR.
+It may be either local or global.
+.TP
+\fBunknown \fIcmd \fR?\fIarg arg ...\fR?
+This procedure is invoked automatically by the Tcl interpreter
+whenever the name of a command doesn't exist.
+The \fBunknown\fR procedure receives as its arguments the
+name and arguments of the missing command.
+.VS
+\fBUnknown\fR first calls \fBauto_load\fR to load the command.
+.VE
+If this succeeds, then it executes the original command with its
+original arguments.
+If the auto-load fails then \fBunknown\fR calls \fBauto_execok\fR
+to see if there is an executable file by the name \fIcmd\fR.
+If so, it invokes the Tcl \fBexec\fR command
+with \fIcmd\fR and all the \fIargs\fR as arguments.
+If \fIcmd\fR can't be auto-executed, \fBunknown\fR checks to
+see if the command was invoked at top-level and outside of any
+script.  If so, then \fBunknown\fR takes takes two additional steps.
+First, it sees if \fIcmd\fR has one of the following three forms:
+\fB!!\fR, \fB!\fIevent\fR, or \fB^\fIold\fB^\fInew\fR?\fB^\fR?.
+If so, then \fBunknown\fR carries out history substitution
+in the same way that \fBcsh\fR would for these constructs.
+Second, and last, \fBunknown\fR checks to see if \fIcmd\fR is
+a unique abbreviation for an existing Tcl command.
+If so, it expands the command name and executes the command with
+the original arguments.
+If none of the above efforts has been able to execute
+the command, \fBunknown\fR generates an error return.
+If the global variable \fBauto_noload\fR is defined, then the auto-load
+step is skipped.
+If the global variable \fBauto_noexec\fR is defined then the
+auto-exec step is skipped.
+Under normal circumstances the return value from \fBunknown\fR
+is the return value from the command that was eventually
+executed.
+
+.SH "VARIABLES"
+.PP
+The following global variables are defined or used by the procedures in
+the Tcl library:
+.TP
+\fBauto_execs\fR
+Used by \fBauto_execok\fR to record information about whether
+particular commands exist as executable files.
+.TP
+\fBauto_index\fR
+Used by \fBauto_load\fR to save the index information read from
+disk.
+.TP
+\fBauto_noexec\fR
+If set to any value, then \fBunknown\fR will not attempt to auto-exec
+any commands.
+.TP
+\fBauto_noload\fR
+If set to any value, then \fBunknown\fR will not attempt to auto-load
+any commands.
+.TP
+\fBauto_path\fR
+If set, then it must contain a valid Tcl list giving directories to
+search during auto-load operations.
+.TP
+\fBenv(TCL_LIBRARY)\fR
+If set, then it specifies the location of the directory containing
+library scripts (the value of this variable will be returned by
+the command \fBinfo library\fR).  If this variable isn't set then
+a default value is used.
+.TP
+\fBenv(TCLLIBPATH)\fR
+If set, then it must contain a valid Tcl list giving directories to
+search during auto-load operations.
+This variable is only used if \fBauto_path\fR is not defined.
+.TP
+\fBunknown_active\fR
+This variable is set by \fBunknown\fR to indicate that it is active.
+It is used to detect errors where \fBunknown\fR recurses on itself
+infinitely.
+The variable is unset before \fBunknown\fR returns.
+
+.SH KEYWORDS

+
+.SH DESCRIPTION
+.PP
+This command searches the elements of \fIlist\fR to see if one
+of them matches \fIpattern\fR.
+If so, the command returns the index of the first matching
+element.
+If not, the command returns \fB\-1\fR.
+.VS
+The \fImode\fR argument indicates how the elements of the list are to
+be matched against \fIpattern\fR and it must have one of the following
+values:
+.TP
+\fB\-exact\fR
+The list element must contain exactly the same string as \fIpattern\fR.
+.TP
+\fB\-glob\fR
+\fIPattern\fR is a glob-style pattern which is matched against each list
+element using the same rules as the \fBstring match\fR command.
+.TP
+\fB\-regexp\fR
+\fIPattern\fR is treated as a regular expression and matched against
+each list element using the same rules as the \fBregexp\fR command.
+.PP
+If \fImode\fR is omitted then it defaults to \fB\-glob\fR.

+lsort \- Sort the elements of a list
+.SH SYNOPSIS
+\fBlsort \fR?\fIswitches\fR? \fIlist\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+This command sorts the elements of \fIlist\fR, returning a new
+list in sorted order.  By default ASCII sorting is used with
+the result returned in increasing order.
+.VS
+However, any of the
+following switches may be specified before \fIlist\fR to
+control the sorting process (unique abbreviations are accepted):
+.TP 20
+\fB\-ascii\fR
+Use string comparison with ASCII collation order.  This is
+the default.
+.TP 20
+\fB\-integer\fR
+Convert list elements to integers and use integer comparison.
+.TP 20
+\fB\-real\fR
+Convert list elements to floating-point values and use floating
+comparison.
+.TP 20
+\fB\-command\0\fIcommand\fR
+Use \fIcommand\fR as a comparison command.
+To compare two elements, evaluate a Tcl script consisting of
+\fIcommand\fR with the two elements appended as additional
+arguments.  The script should return an integer less than,
+equal to, or greater than zero if the first element is to
+be considered less than, equal to, or greater than the second,
+respectively.
+.TP 20
+\fB\-increasing\fR
+Sort the list in increasing order (``smallest'' items first).
+This is the default.
+.TP 20
+\fB\-decreasing\fR
+Sort the list in decreasing order (``largest'' items first).

+.SH SYNOPSIS
+.VS
+\fBopen \fIfileName\fR ?\fIaccess\fR? ?\fIpermissions\fR?
+.VE
+.BE
+
+.SH DESCRIPTION
+.PP
+This command opens a file and returns an identifier
+that may be used in future invocations
+of commands like \fBread\fR, \fBputs\fR, and \fBclose\fR.
+\fIFileName\fR gives the name of the file to open; if it starts with
+a tilde then tilde substitution is performed as described for
+\fBTcl_TildeSubst\fR.
+If the first character of \fIfileName\fR is ``|'' then the
+remaining characters of \fIfileName\fR are treated as a command
+pipeline to invoke, in the same style as for \fBexec\fR.
+In this case, the identifier returned by \fBopen\fR may be used
+to write to the command's input pipe or read from its output pipe.
+.PP
+The \fIaccess\fR argument indicates the way in which the file
+(or command pipeline) is to be accessed.
+.VS
+It may take two forms, either a string in the form that would be
+passed to the \fBfopen\fR library procedure or a list of POSIX
+access flags.
+It defaults to ``\fBr\fR''.
+In the first form \fIaccess\fR may have any of the following values:
+.VE
+.TP 15
+\fBr\fR
+Open the file for reading only; the file must already exist.
+.TP 15
+\fBr+\fR
+Open the file for both reading and writing; the file must
+already exist.
+.TP 15
+\fBw\fR
+Open the file for writing only.  Truncate it if it exists.  If it doesn't
+exist, create a new file.
+.TP 15
+\fBw+\fR
+Open the file for reading and writing.  Truncate it if it exists.
+If it doesn't exist, create a new file.
+.TP 15
+\fBa\fR
+Open the file for writing only.  The file must already exist, and the file
+is positioned so that new data is appended to the file.
+.TP 15
+\fBa+\fR
+Open the file for reading and writing.  If the file doesn't exist,
+create a new empty file.
+Set the initial access position  to the end of the file.
+.PP
+In the second form, \fIaccess\fR consists of a list of any of the
+.VS
+following flags, all of which have the standard POSIX meanings.
+One of the flags must be either \fBRDONLY\fR, \fBWRONLY\fR or \fBRDWR\fR.
+.TP 15
+\fBRDONLY\fR
+Open the file for reading only.
+.TP 15
+\fBWRONLY\fR
+Open the file for writing only.
+.TP 15
+\fBRDWR\fR
+Open the file for both reading and writing.
+.TP 15
+\fBAPPEND\fR
+Set the file pointer to the end of the file prior to each write.
+.TP 15
+\fBCREAT\fR
+Create the file if it doesn't already exist (without this flag it
+is an error for the file not to exist).
+.TP 15
+\fBEXCL\fR
+If \fBCREAT\fR is specified also, an error is returned if the
+file already exists.
+.TP 15
+\fBNOCTTY\fR
+If the file is a terminal device, this flag prevents the file from
+becoming the controlling terminal of the process.
+.TP 15
+\fBNONBLOCK\fR
+Prevents the process from blocking while opening the file.
+For details refer to your system documentation on the \fBopen\fR system
+call's \fBO_NONBLOCK\fR flag.
+.TP 15
+\fBTRUNC\fR
+If the file exists it is truncated to zero length.
+.PP
+If a new file is created as part of opening it, \fIpermissions\fR
+(an integer) is used to set the permissions for the new file in
+conjunction with the process's file mode creation mask.
+\fIPermissions\fR defaults to 0666.
+.VE
+.PP
+If a file is opened for both reading and writing then \fBseek\fR
+must be invoked between a read and a write, or vice versa (this
+restriction does not apply to command pipelines opened with \fBopen\fR).
+When \fIfileName\fR specifies a command pipeline and a write-only access
+is used, then standard output from the pipeline is directed to the
+current standard output unless overridden by the command.
+When \fIfileName\fR specifies a command pipeline and a read-only access
+is used, then standard input from the pipeline is taken from the
+current standard input unless overridden by the command.

+In this case the \fBpid\fR command will return a list whose elements
+are the process identifiers of all the processes in the pipeline,

+.SH NAME
+proc \- Create a Tcl procedure
+.SH SYNOPSIS
+\fBproc \fIname args body\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+The \fBproc\fR command creates a new Tcl procedure named
+\fIname\fR, replacing
+any existing command or procedure there may have been by that name.
+Whenever the new command is invoked, the contents of \fIbody\fR will
+be executed by the Tcl interpreter.
+\fIArgs\fR specifies the formal arguments to the
+procedure.  It consists of a list, possibly empty, each of whose
+elements specifies
+one argument.  Each argument specifier is also a list with either
+one or two fields.  If there is only a single field in the specifier
+then it is the name of the argument; if there are two fields, then
+the first is the argument name and the second is its default value.
+.PP
+When \fIname\fR is invoked a local variable
+will be created for each of the formal arguments to the procedure; its
+value will be the value of corresponding argument in the invoking command
+or the argument's default value.
+Arguments with default values need not be
+specified in a procedure invocation.  However, there must be enough
+actual arguments for all the
+formal arguments that don't have defaults, and there must not be any extra
+actual arguments.  There is one special case to permit procedures with
+variable numbers of arguments.  If the last formal argument has the name
+\fBargs\fR, then a call to the procedure may contain more actual arguments
+than the procedure has formals.  In this case, all of the actual arguments
+starting at the one that would be assigned to \fBargs\fR are combined into
+a list (as if the \fBlist\fR command had been used); this combined value
+is assigned to the local variable \fBargs\fR.
+.PP
+When \fIbody\fR is being executed, variable names normally refer to
+local variables, which are created automatically when referenced and
+deleted when the procedure returns.  One local variable is automatically
+created for each of the procedure's arguments.
+Global variables can only be accessed by invoking
+the \fBglobal\fR command or the \fBupvar\fR command.
+.PP
+The \fBproc\fR command returns an empty string.  When a procedure is
+invoked, the procedure's return value is the value specified in a
+\fBreturn\fR command.  If the procedure doesn't execute an explicit
+\fBreturn\fR, then its return value is the value of the last command
+executed in the procedure's body.
+If an error occurs while executing the procedure
+body, then the procedure-as-a-whole will return that same error.

+\fBputs \fR?\fB\-nonewline\fR? ?\fIfileId\fR? \fIstring\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+Writes the characters given by \fIstring\fR to the file given
+by \fIfileId\fR.
+\fIFileId\fR must have been the return
+value from a previous call to \fBopen\fR, or it may be
+\fBstdout\fR or \fBstderr\fR to refer to one of the standard I/O
+channels; it must refer to a file that was opened for
+writing.
+If no \fIfileId\fR is specified then it defaults to \fBstdout\fR.
+\fBPuts\fR normally outputs a newline character after \fIstring\fR,
+but this feature may be suppressed by specifying the \fB\-nonewline\fR
+switch.
+Output to files is buffered internally by Tcl; the \fBflush\fR
+command may be used to force buffered characters to be output.

+regexp \- Match a regular expression against a string
+.SH SYNOPSIS
+\fBregexp \fR?\fIswitches\fR? \fIexp string \fR?\fImatchVar\fR? ?\fIsubMatchVar subMatchVar ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+Determines whether the regular expression \fIexp\fR matches part or
+all of \fIstring\fR and returns 1 if it does, 0 if it doesn't.
+.LP
+If additional arguments are specified after \fIstring\fR then they
+are treated as the names of variables in which to return
+information about which part(s) of \fIstring\fR matched \fIexp\fR.
+\fIMatchVar\fR will be set to the range of \fIstring\fR that
+matched all of \fIexp\fR.  The first \fIsubMatchVar\fR will contain
+the characters in \fIstring\fR that matched the leftmost parenthesized
+subexpression within \fIexp\fR, the next \fIsubMatchVar\fR will
+contain the characters that matched the next parenthesized
+subexpression to the right in \fIexp\fR, and so on.
+.LP
+If the initial arguments to \fBregexp\fR start with \fB\-\fR then
+.VS
+they are treated as switches.  The following switches are
+currently supported:
+.TP 10
+\fB\-nocase\fR
+Causes upper-case characters in \fIstring\fR to be treated as
+lower case during the matching process.
+.TP 10
+\fB\-indices\fR
+Changes what is stored in the \fIsubMatchVar\fRs. 
+Instead of storing the matching characters from \fBstring\fR,
+each variable
+will contain a list of two decimal strings giving the indices
+in \fIstring\fR of the first and last characters in the matching
+range of characters.
+.TP 10
+\fB\-\|\-\fR
+Marks the end of switches.  The argument following this one will
+be treated as \fIexp\fR even if it starts with a \fB\-.
+.VE
+.LP
+If there are more \fIsubMatchVar\fR's than parenthesized
+subexpressions within \fIexp\fR, or if a particular subexpression
+in \fIexp\fR doesn't match the string (e.g. because it was in a
+portion of the expression that wasn't matched), then the corresponding
+\fIsubMatchVar\fR will be set to ``\fB\-1 \-1\fR'' if \fB\-indices\fR
+has been specified or to an empty string otherwise.
+
+.SH "REGULAR EXPRESSIONS"
+.PP
+Regular expressions are implemented using Henry Spencer's package
+(thanks, Henry!),
+and much of the description of regular expressions below is copied verbatim
+from his manual entry.
+.PP
+A regular expression is zero or more \fIbranches\fR, separated by ``|''.
+It matches anything that matches one of the branches.
+.PP
+A branch is zero or more \fIpieces\fR, concatenated.
+It matches a match for the first, followed by a match for the second, etc.
+.PP
+A piece is an \fIatom\fR possibly followed by ``*'', ``+'', or ``?''.
+An atom followed by ``*'' matches a sequence of 0 or more matches of the atom.
+An atom followed by ``+'' matches a sequence of 1 or more matches of the atom.
+An atom followed by ``?'' matches a match of the atom, or the null string.
+.PP
+An atom is a regular expression in parentheses (matching a match for the
+regular expression), a \fIrange\fR (see below), ``.''
+(matching any single character), ``^'' (matching the null string at the
+beginning of the input string), ``$'' (matching the null string at the
+end of the input string), a ``\e'' followed by a single character (matching
+that character), or a single character with no other significance
+(matching that character).
+.PP
+A \fIrange\fR is a sequence of characters enclosed in ``[]''.
+It normally matches any single character from the sequence.
+If the sequence begins with ``^'',
+it matches any single character \fInot\fR from the rest of the sequence.
+If two characters in the sequence are separated by ``\-'', this is shorthand
+for the full list of ASCII characters between them
+(e.g. ``[0-9]'' matches any decimal digit).
+To include a literal ``]'' in the sequence, make it the first character
+(following a possible ``^'').
+To include a literal ``\-'', make it the first or last character.
+
+.SH "CHOOSING AMONG ALTERNATIVE MATCHES"
+.PP
+In general there may be more than one way to match a regular expression
+to an input string.  For example, consider the command
+.DS
+\fBregexp  (a*)b*  aabaaabb  x  y
+.DE
+Considering only the rules given so far, \fBx\fR and \fBy\fR could
+end up with the values \fBaabb\fR and \fBaa\fR, \fBaaab\fR and \fBaaa\fR,
+\fBab\fR and \fBa\fR, or any of several other combinations.
+To resolve this potential ambiguity \fBregexp\fR chooses among
+alternatives using the rule ``first then longest''.
+In other words, it consders the possible matches in order working
+from left to right across the input string and the pattern, and it
+attempts to match longer pieces of the input string before shorter
+ones.  More specifically, the following rules apply in decreasing
+order of priority:
+.IP [1]
+If a regular expression could match two different parts of an input string
+then it will match the one that begins earliest.
+.IP [2]
+If a regular expression contains \fB|\fR operators then the leftmost
+matching sub-expression is chosen.
+.IP [3]
+In \fB*\fR, \fB+\fR, and \fB?\fR constructs, longer matches are chosen
+in preference to shorter ones.
+.IP [4]
+In sequences of expression components the components are considered
+from left to right.
+.LP
+In the example from above, \fB(a*)b*\fR matches \fBaab\fR:  the \fB(a*)\fR
+portion of the pattern is matched first and it consumes the leading
+\fBaa\fR; then the \fBb*\fR portion of the pattern consumes the
+next \fBb\fR.  Or, consider the following example:
+.DS
+\fBregexp  (ab|a)(b*)c  abc  x  y  z
+.DE
+After this command \fBx\fR will be \fBabc\fR, \fBy\fR will be
+\fBab\fR, and \fBz\fR will be an empty string.
+Rule 4 specifies that \fB(ab|a)\fR gets first shot at the input
+string and Rule 2 specifies that the \fBab\fR sub-expression
+is checked before the \fBa\fR sub-expression.
+Thus the \fBb\fR has already been claimed before the \fB(b*)\fR
+component is checked and \fB(b*)\fR must match an empty string.

+.SH SYNOPSIS
+\fBregsub \fR?\fIswitches\fR? \fIexp string subSpec varName\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+This command matches the regular expression \fIexp\fR against
+\fIstring\fR,
+.VS
+and it copies \fIstring\fR to the variable whose name is
+given by \fIvarName\fR.
+The command returns 1 if there is a match and 0 if there isn't.
+If there is a match, then while copying \fIstring\fR to \fIvarName\fR
+the portion of \fIstring\fR that
+.VE
+matched \fIexp\fR is replaced with \fIsubSpec\fR.
+If \fIsubSpec\fR contains a ``&'' or ``\e0'', then it is replaced
+in the substitution with the portion of \fIstring\fR that
+matched \fIexp\fR.
+If \fIsubSpec\fR contains a ``\e\fIn\fR'', where \fIn\fR is a digit
+between 1 and 9, then it is replaced in the substitution with
+the portion of \fIstring\fR that matched the \fIn\fR-th
+parenthesized subexpression of \fIexp\fR.
+Additional backslashes may be used in \fIsubSpec\fR to prevent special
+interpretation of ``&'' or ``\e0'' or ``\e\fIn\fR'' or
+backslash.
+The use of backslashes in \fIsubSpec\fR tends to interact badly
+with the Tcl parser's use of backslashes, so it's generally
+safest to enclose \fIsubSpec\fR in braces if it includes
+backslashes.
+.LP
+If the initial arguments to \fBregexp\fR start with \fB\-\fR then
+.VS
+they are treated as switches.  The following switches are
+currently supported:
+.TP 10
+\fB\-all\fR
+All ranges in \fIstring\fR that match \fIexp\fR are found and
+substitution is performed for each of these ranges.
+Without this switch only the first
+matching range is found and substituted.
+If \fB\-all\fR is specified, then ``&'' and ``\e\fIn\fR''
+sequences are handled for each substitution using the information
+from the corresponding match.
+.TP 10
+\fB\-nocase\fR
+Upper-case characters in \fIstring\fR will be converted to lower-case
+before matching against \fIexp\fR;  however, substitutions specified
+by \fIsubSpec\fR use the original unconverted form of \fIstring\fR.
+.TP 10
+\fB\-\|\-\fR
+Marks the end of switches.  The argument following this one will
+be treated as \fIexp\fR even if it starts with a \fB\-.

+.TP 10
+\fBok\fR
+Normal return:  same as if the option is omitted.

+.TP 10
+\fBreturn\fR
+The current procedure will return with a completion code of

+.TP 10
+\fBbreak\fR
+The current procedure will return with a completion code of
+TCL_BREAK, which will terminate the innermost nested loop in

+\fBcontinue\fR
+The current procedure will return with a completion code of
+TCL_CONTINUE, which will terminate the current iteration of

+.TP 10
+\fIvalue\fR
+\fIValue\fR must be an integer;  it will be returned as the
+completion code for the current procedure.
+.LP
+The \fB\-code\fR option is rarely used.
+It is provided so that procedures that implement
+new control structures can reflect exceptional conditions back to
+their callers.
+.PP
+Two additional options, \fB\-errorinfo\fR and \fB\-errorcode\fR,
+may be used to provide additional information during error
+returns.
+These options are ignored unless \fIcode\fR is \fBerror\fR.

+Typically the \fIinfo\fR value is supplied from the value left
+in \fBerrorInfo\fR after a \fBcatch\fR command trapped an error within
+the procedure.
+.PP
+If the \fB\-errorcode\fR option is specified then \fIcode\fR provides

+
+.SH INTRODUCTION
+.PP
+This command parses fields from an input string in the same fashion
+as the ANSI C \fBsscanf\fR procedure and returns a count of the number
+of fields sucessfully parsed.
+\fIString\fR gives the input to be parsed and \fIformat\fR indicates
+how to parse it, using \fB%\fR conversion specifiers as in \fBsscanf\fR.
+Each \fIvarName\fR gives the name of a variable; when a field is

+\fBScan\fR operates by scanning \fIstring\fR and \fIformatString\fR together.
+If the next character in \fIformatString\fR is a blank or tab then it
+is ignored.
+Otherwise, if it isn't a \fB%\fR character then it 
+must match the next non-white-space character of \fIstring\fR.
+When a \fB%\fR is encountered in \fIformatString\fR, it indicates
+the start of a conversion specifier.
+A conversion specifier contains three fields after the \fB%\fR:
+a \fB*\fR, which indicates that the converted value is to be discarded 
+instead of assigned to a variable; a number indicating a maximum field
+width; and a conversion character.
+All of these fields are optional except for the conversion character.
+.PP
+When \fBscan\fR finds a conversion specifier in \fIformatString\fR, it
+first skips any white-space characters in \fIstring\fR.
+Then it converts the next input characters according to the 
+conversion specifier and stores the result in the variable given
+by the next argument to \fBscan\fR.
+The following conversion characters are supported:
+.TP 10
+\fBd\fR
+The input field must be a decimal integer.
+It is read in and the value is stored in the variable as a decimal string.
+.TP 10
+\fBo\fR
+The input field must be an octal integer. It is read in and the 
+value is stored in the variable as a decimal string.
+.TP 10
+\fBx\fR
+The input field must be a hexadecimal integer. It is read in 
+and the value is stored in the variable as a decimal string.
+.TP 10
+\fBc\fR
+A single character is read in and its binary value is stored in 
+the variable as a decimal string.
+Initial white space is not skipped in this case, so the input
+field may be a white-space character.
+This conversion is different from the ANSI standard in that the
+input field always consists of a single character and no field
+width may be specified.
+.TP 10
+\fBs\fR
+The input field consists of all the characters up to the next 
+white-space character; the characters are copied to the variable.
+.TP 10
+\fBe\fR or \fBf\fR or \fBg\fR
+The input field must be a floating-point number consisting 
+of an optional sign, a string of decimal digits possibly con
+taining a decimal point, and an optional exponent consisting 
+of an \fBe\fR or \fBE\fR followed by an optional sign and a string of 
+decimal digits.
+It is read in and stored in the variable as a floating-point string.
+.TP 10
+\fB[\fIchars\fB]
+The input field consists of any number of characters in 
+\fIchars\fR.
+The matching string is stored in the variable.
+If the first character between the brackets is a \fB]\fR then
+it is treated as part of \fIchars\fR rather than the closing
+bracket for the set.
+.TP 10
+\fB[^\fIchars\fB]
+The input field consists of any number of characters not in 
+\fIchars\fR.
+The matching string is stored in the variable.
+If the character immediately following the \fB^\fR is a \fB]\fR then it is 
+treated as part of the set rather than the closing bracket for 
+the set.
+.LP
+The number of characters read from the input for a conversion is the
+largest number that makes sense for that particular conversion (e.g.
+as many decimal digits as possible for \fB%d\fR, as 
+many octal digits as possible for \fB%o\fR, and so on).
+The input field for a given conversion terminates either when a
+white-space character is encountered or when the maximum field 
+width has been reached, whichever comes first.
+If a \fB*\fR is present in the conversion specifier 
+then no variable is assigned and the next scan argument is not consumed.
+
+.SH "DIFFERENCES FROM ANSI SSCANF"
+.PP
+The behavior of the \fBscan\fR command is the same as the behavior of
+the ANSI C \fBsscanf\fR procedure except for the following differences:
+.IP [1]
+.VS
+\fB%p\fR and \fB%n\fR conversion specifiers are not currently
+supported.
+.VE
+.IP [2]
+For \fB%c\fR conversions a single character value is
+converted to a decimal string, which is then assigned to the
+corresponding \fIvarName\fR;
+no field width may be specified for this conversion.
+.IP [3]
+.VS
+The \fBl\fR, \fBh\fR, and \fBL\fR modifiers are ignored;  integer
+values are always converted as if there were no modifier present
+and real values are always converted as if the \fBl\fR modifier
+were present (i.e. type \fBdouble\fR is used for the internal
+representation).

+.PP
+Change the current access position for \fIfileId\fR.
+\fIFileId\fR must have been the return
+value from a previous call to \fBopen\fR, or it may be \fBstdin\fR,
+\fBstdout\fR, or \fBstderr\fR to refer to one of the standard I/O
+channels.
+The \fIoffset\fR and \fIorigin\fR arguments specify the position at
+which the next read or write will occur for \fIfileId\fR.
+\fIOffset\fR must be an integer (which may be negative) and \fIorigin\fR
+must be one of the following:
+.TP
+\fBstart\fR
+The new access position will be \fIoffset\fR bytes from the start
+of the file.
+.TP
+\fBcurrent\fR
+The new access position will be \fIoffset\fR bytes from the current
+access position; a negative \fIoffset\fR moves the access position
+backwards in the file.
+.TP
+\fBend\fR
+The new access position will be \fIoffset\fR bytes from the end of
+the file.  A negative \fIoffset\fR places the access position before
+the end-of-file, and a positive \fIoffset\fR places the access position
+after the end-of-file.
+.LP
+The \fIorigin\fR argument defaults to \fBstart\fR.

+\fBstring \fIoption arg \fR?\fIarg ...?\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+Performs one of several string operations, depending on \fIoption\fR.
+The legal \fIoption\fRs (which may be abbreviated) are:
+.TP
+\fBstring compare \fIstring1 string2\fR
+Perform a character-by-character comparison of strings \fIstring1\fR and
+\fIstring2\fR in the same way as the C \fBstrcmp\fR procedure.  Return
+\-1, 0, or 1, depending on whether \fIstring1\fR is lexicographically
+less than, equal to, or greater than \fIstring2\fR.
+.TP
+\fBstring first \fIstring1 string2\fR
+Search \fIstring2\fR for a sequence of characters that exactly match
+the characters in \fIstring1\fR.  If found, return the index of the
+first character in the first such match within \fIstring2\fR.  If not
+found, return \-1.
+.TP
+\fBstring index \fIstring charIndex\fR
+Returns the \fIcharIndex\fR'th character of the \fIstring\fR
+argument.  A \fIcharIndex\fR of 0 corresponds to the first
+character of the string.
+If \fIcharIndex\fR is less than 0 or greater than
+or equal to the length of the string then an empty string is
+returned.
+.TP
+\fBstring last \fIstring1 string2\fR
+Search \fIstring2\fR for a sequence of characters that exactly match
+the characters in \fIstring1\fR.  If found, return the index of the
+first character in the last such match within \fIstring2\fR.  If there
+is no match, then return \-1.
+.TP
+\fBstring length \fIstring\fR
+Returns a decimal string giving the number of characters in \fIstring\fR.
+.TP
+\fBstring match \fIpattern\fR \fIstring\fR
+See if \fIpattern\fR matches \fIstring\fR; return 1 if it does, 0
+if it doesn't.  Matching is done in a fashion similar to that
+used by the C-shell.  For the two strings to match, their contents
+must be identical except that the following special sequences
+may appear in \fIpattern\fR:
+.RS
+.IP \fB*\fR 10
+Matches any sequence of characters in \fIstring\fR,
+including a null string.
+.IP \fB?\fR 10
+Matches any single character in \fIstring\fR.
+.IP \fB[\fIchars\fB]\fR 10
+Matches any character in the set given by \fIchars\fR.  If a sequence
+of the form
+\fIx\fB\-\fIy\fR appears in \fIchars\fR, then any character
+between \fIx\fR and \fIy\fR, inclusive, will match.
+.IP \fB\e\fIx\fR 10
+Matches the single character \fIx\fR.  This provides a way of
+avoiding the special interpretation of the characters
+\fB*?[]\e\fR in \fIpattern\fR.
+.RE
+.TP
+\fBstring range \fIstring first last\fR
+Returns a range of consecutive characters from \fIstring\fR, starting
+with the character whose index is \fIfirst\fR and ending with the
+character whose index is \fIlast\fR.  An index of 0 refers to the
+first character of the string.  \fILast\fR may be \fBend\fR (or any
+abbreviation of it) to refer to the last character of the string.
+If \fIfirst\fR is less than zero then it is treated as if it were zero, and
+if \fIlast\fR is greater than or equal to the length of the string then
+it is treated as if it were \fBend\fR.  If \fIfirst\fR is greater than
+\fIlast\fR then an empty string is returned.
+.TP
+\fBstring tolower \fIstring\fR
+Returns a value equal to \fIstring\fR except that all upper case
+letters have been converted to lower case.
+.TP
+\fBstring toupper \fIstring\fR
+Returns a value equal to \fIstring\fR except that all lower case
+letters have been converted to upper case.
+.TP
+\fBstring trim \fIstring\fR ?\fIchars\fR?
+Returns a value equal to \fIstring\fR except that any leading
+or trailing characters from the set given by \fIchars\fR are
+removed.
+If \fIchars\fR is not specified then white space is removed
+(spaces, tabs, newlines, and carriage returns).
+.TP
+\fBstring trimleft \fIstring\fR ?\fIchars\fR?
+Returns a value equal to \fIstring\fR except that any

+.br
+\fBswitch\fI \fR?\fIoptions\fR?\fI string \fR{\fIpattern body \fR?\fIpattern body \fR...?}
+.BE
+
+.SH DESCRIPTION
+.PP
+The \fBswitch\fR command matches its \fIstring\fR argument against each of
+the \fIpattern\fR arguments in order.
+As soon as it finds a \fIpattern\fR that matches \fIstring\fR it
+evaluates the following \fIbody\fR argument by passing it recursively
+to the Tcl interpreter and returns the result of that evaluation.
+If the last \fIpattern\fR argument is \fBdefault\fR then it matches
+anything.
+If no \fIpattern\fR argument
+matches \fIstring\fR and no default is given, then the \fBswitch\fR
+command returns an empty string.
+.PP
+If the initial arguments to \fBswitch\fR start with \fB\-\fR then
+they are treated as options.  The following options are
+currently supported:
+.TP 10
+\fB\-exact\fR
+Use exact matching when comparing \fIstring\fR to a pattern.  This
+is the default.
+.TP 10
+\fB\-glob\fR
+When matching \fIstring\fR to the patterns, use glob-style matching
+(i.e. the same as implemented by the \fBstring match\fR command).
+.TP 10
+\fB\-regexp\fR
+When matching \fIstring\fR to the patterns, use regular
+expression matching
+(i.e. the same as implemented by the \fBregexp\fR command).
+.TP 10
+\fB\-\|\-\fR
+Marks the end of options.  The argument following this one will
+be treated as \fIstring\fR even if it starts with a \fB\-.
+.PP
+Two syntaxes are provided for the \fIpattern\fR and \fIbody\fR arguments.
+The first uses a separate argument for each of the patterns and commands;
+this form is convenient if substitutions are desired on some of the
+patterns or commands.
+The second form places all of the patterns and commands together into
+a single argument; the argument must have proper list structure, with
+the elements of the list being the patterns and commands.
+The second form makes it easy to construct multi-line switch commands,
+since the braces around the whole list make it unnecessary to include a
+backslash at the end of each line.
+Since the \fIpattern\fR arguments are in braces in the second form,
+no command or variable substitutions are performed on them;  this makes
+the behavior of the second form different than the first form in some
+cases.
+.PP
+If a \fIbody\fR is specified as ``\fB\-\fR'' it means that the \fIbody\fR
+for the next pattern should also be used as the body for this
+pattern (if the next pattern also has a body of ``\fB\-\fR''
+then the body after that is used, and so on).
+This feature makes it possible to share a single \fIbody\fR among
+several patterns.
+.PP
+Below are some examples of \fBswitch\fR commands:
+.DS
+\fBswitch\0abc\0a\0\-\0b\0{format 1}\0abc\0{format 2}\0default\0{format 3}
+.DE
+will return \fB2\fR, 
+.DS
+.ta .5c 1c
+\fBswitch\0\-regexp\0aaab {

+.SH NAME
+tclsh \- Simple shell containing Tcl interpreter
+.SH SYNOPSIS
+\fBtclsh\fR ?\fIfileName arg arg ...\fR?\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+\fBTclsh\fR is a shell-like application that reads Tcl commands
+from its standard input or from a file and evaluates them.
+If invoked with no arguments then it runs interactively, reading
+Tcl commands from standard input and printing command results and
+error messages to standard output.
+It runs until the \fBexit\fR command is invoked or until it
+reaches end-of-file on its standard input.
+If there exists a file \fB.tclshrc\fR in the home directory of
+the user, \fBtclsh\fR evaluates the file as a Tcl script
+just before reading the first command from standard input.
+
+.SH "SCRIPT FILES"
+.PP
+If \fBtclsh\fR is invoked with arguments then the first argument
+is the name of a script file and any additional arguments
+are made available to the script as variables (see below).
+Instead of reading commands from standard input \fBtclsh\fR will
+read Tcl commands from the named file;  \fBtclsh\fR will exit
+when it reaches the end of the file.
+There is no automatic evaluation of \fB.tclshrc\fR in this
+case, but the script file can always \fBsource\fR it if desired.
+.PP
+If you create a Tcl script in a file whose first line is
+.DS
+\fB#!/usr/local/bin/tclsh
+.DE
+then you can invoke the script file directly from your shell if
+you mark the file as executable.
+This assumes that \fBtclsh\fR has been installed in the default
+location in /usr/local/bin;  if it's installed somewhere else
+then you'll have to modify the above line to match.
+
+.SH "VARIABLES"
+.PP
+\fBTclsh\fR sets the following Tcl variables:
+.TP 15
+\fBargc\fR
+Contains a count of the number of \fIarg\fR arguments (0 if none),
+not including the name of the script file.
+.TP 15
+\fBargv\fR
+Contains a Tcl list whose elements are the \fIarg\fR arguments,
+in order, or an empty string if there are no \fIarg\fR arguments.
+.TP 15
+\fBargv0\fR
+Contains \fIfileName\fR if it was specified.
+Otherwise, contains the name by which \fBtclsh\fR was invoked.
+.TP 15
+\fBtcl_interactive\fR
+Contains 1 if \fBtclsh\fR is running interactively (no
+\fIfileName\fR was specified and standard input is a terminal-like
+device), 0 otherwise.
+.LP
+
+.SH PROMPTS
+.PP
+When \fBtclsh\fR is invoked interactively it normally prompts for each
+command with ``\fB% \fR''.  You can change the prompt by setting the
+variables \fBtcl_prompt1\fR and \fBtcl_prompt2\fR.  If variable
+\fBtcl_prompt1\fR exists then it must consist of a Tcl script
+to output a prompt;  instead of outputting a prompt \fBtclsh\fR
+will evaluate the script in \fBtcl_prompt1\fR.
+The variable \fBtcl_prompt2\fR is used in a similar way when
+a newline is typed but the current command isn't yet complete;
+if \fBtcl_prompt2\fR isn't set then no prompt is output for
+incomplete commands.
+
+.SH KEYWORDS

+.SH NAME
+tclvars \- Variables used by Tcl
+.BE
+
+.SH DESCRIPTION
+.PP
+The following global variables are created and managed automatically
+by the Tcl library.  Except where noted below, these variables should
+normally be treated as read-only by application-specific code and by users.
+.TP
+\fBenv\fR
+.br
+This variable is maintained by Tcl as an array
+whose elements are the environment variables for the process.
+Reading an element will return the value of the corresponding
+environment variable.
+Setting an element of the array will modify the corresponding
+environment variable or create a new one if it doesn't already
+exist.
+Unsetting an element of \fBenv\fR will remove the corresponding
+environment variable.
+Changes to the \fBenv\fR array will affect the environment
+passed to children by commands like \fBexec\fR.
+If the entire \fBenv\fR array is unset then Tcl will stop
+monitoring \fBenv\fR accesses and will not update environment
+variables.
+.TP
+\fBerrorCode\fR
+After an error has occurred, this variable will be set to hold
+additional information about the error in a form that is easy
+to process with programs.
+\fBerrorCode\fR consists of a Tcl list with one or more elements.
+The first element of the list identifies a general class of
+errors, and determines the format of the rest of the list.
+The following formats for \fBerrorCode\fR are used by the
+Tcl core; individual applications may define additional formats.
+.RS
+.TP
+\fBARITH\fI code msg\fR
+.VS
+This format is used when an arithmetic error occurs (e.g. an attempt
+to divide by zero in the \fBexpr\fR command).
+\fICode\fR identifies the precise error and \fImsg\fR provides a
+human-readable description of the error.  \fICode\fR will be either
+DIVZERO (for an attempt to divide by zero),
+DOMAIN (if an argument is outside the domain of a function, such as acos(\-3)),
+IOVERFLOW (for integer overflow),
+OVERLFLOW (for a floating-point overflow),
+or UNKNOWN (if the cause of the error cannot be determined).
+.VE
+.TP
+\fBCHILDKILLED\fI pid sigName msg\fR
+This format is used when a child process has been killed because of
+a signal.  The second element of \fBerrorCode\fR will be the
+process's identifier (in decimal).
+The third element will be the symbolic name of the signal that caused
+the process to terminate; it will be one of the names from the
+include file signal.h, such as \fBSIGPIPE\fR.
+The fourth element will be a short human-readable message
+describing the signal, such as ``write on pipe with no readers''
+for \fBSIGPIPE\fR.
+.TP
+\fBCHILDSTATUS\fI pid code\fR
+This format is used when a child process has exited with a non-zero
+exit status.  The second element of \fBerrorCode\fR will be the
+process's identifier (in decimal) and the third element will be the exit
+code returned by the process (also in decimal).
+.TP
+\fBCHILDSUSP\fI pid sigName msg\fR
+This format is used when a child process has been suspended because
+of a signal.
+The second element of \fBerrorCode\fR will be the process's identifier,
+in decimal.
+The third element will be the symbolic name of the signal that caused
+the process to suspend; this will be one of the names from the
+include file signal.h, such as \fBSIGTTIN\fR.
+The fourth element will be a short human-readable message
+describing the signal, such as ``background tty read''
+for \fBSIGTTIN\fR.
+.TP
+\fBNONE\fR
+.br
+This format is used for errors where no additional information is
+available for an error besides the message returned with the
+error.  In these cases \fBerrorCode\fR will consist of a list
+containing a single element whose contents are \fBNONE\fR.
+.TP
+\fBPOSIX \fIerrName msg\fR
+.VS
+If the first element of \fBerrorCode\fR is \fBPOSIX\fR, then
+the error occurred during a POSIX kernel call.
+.VE
+The second element of the list will contain the symbolic name
+of the error that occurred, such as \fBENOENT\fR; this will
+be one of the values defined in the include file errno.h.
+The third element of the list will be a human-readable
+message corresponding to \fIerrName\fR, such as
+``no such file or directory'' for the \fBENOENT\fR case.
+.PP
+To set \fBerrorCode\fR, applications should use library
+procedures such as \fBTcl_SetErrorCode\fR and
+.VS
+\fBTcl_PosixError\fR,
+.VE
+or they may invoke the \fBerror\fR command.
+If one of these methods hasn't been used, then the Tcl
+interpreter will reset the variable to \fBNONE\fR after
+the next error.
+.RE
+.TP
+\fBerrorInfo\fR
+After an error has occurred, this string will contain one or more lines
+identifying the Tcl commands and procedures that were being executed
+when the most recent error occurred.
+Its contents take the form of a stack trace showing the various
+nested Tcl commands that had been invoked at the time of the error.
+.TP
+\fBtcl_precision\fR
+.VS
+If this variable is set, it must contain a decimal number giving the
+number of significant digits to include when converting floating-point
+values to strings.
+If this variable is not set then 6 digits are included.
+17 digits is ``perfect'' for IEEE floating-point in that it allows
+double-precision values to be converted to strings and back to
+binary with no loss of precision.
+.VE
+
+.SH KEYWORDS
+arithmetic, error, environment, POSIX, precision, subprocess, variables

+.SH SYNOPSIS
+\fBtrace \fIoption\fR ?\fIarg arg ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command causes Tcl commands to be executed whenever certain operations are
+invoked.  At present, only variable tracing is implemented. The
+legal \fIoption\fR's (which may be abbreviated) are:
+.TP
+\fBtrace variable \fIname ops command\fR
+Arrange for \fIcommand\fR to be executed whenever variable \fIname\fR
+is accessed in one of the ways given by \fIops\fR.  \fIName\fR may
+refer to a normal variable, an element of an array, or to an array
+as a whole (i.e. \fIname\fR may be just the name of an array, with no
+parenthesized index).  If \fIname\fR refers to a whole array, then
+\fIcommand\fR is invoked whenever any element of the array is
+manipulated.
+.RS
+.LP
+\fIOps\fR indicates which operations are of interest, and consists of
+one or more of the following letters:
+.RS
+.TP
+\fBr\fR
+Invoke \fIcommand\fR whenever the variable is read.
+.TP
+\fBw\fR
+Invoke \fIcommand\fR whenever the variable is written.
+.TP
+\fBu\fR
+Invoke \fIcommand\fR whenever the variable is unset.  Variables
+can be unset explicitly with the \fBunset\fR command, or
+implicitly when procedures return (all of their local variables
+are unset).  Variables are also unset when interpreters are
+deleted, but traces will not be invoked because there is no
+interpreter in which to execute them.
+.RE
+.LP
+When the trace triggers, three arguments are appended to
+\fIcommand\fR so that the actual command is as follows:
+.DS C
+\fIcommand name1 name2 op\fR
+.DE
+\fIName1\fR and \fIname2\fR give the name(s) for the variable
+being accessed:  if the variable is a scalar then \fIname1\fR
+gives the variable's name and \fIname2\fR is an empty string;
+if the variable is an array element then \fIname1\fR gives the
+name of the array and name2 gives the index into the array;
+if an entire array is being deleted and the trace was registered
+on the overall array, rather than a single element, then \fIname1\fR
+gives the array name and \fIname2\fR is an empty string.
+\fIOp\fR indicates what operation is being performed on the
+variable, and is one of \fBr\fR, \fBw\fR, or \fBu\fR as
+defined above.
+.LP
+\fICommand\fR executes in the same context as the code that invoked
+the traced operation:  if the variable was accessed as part of a
+Tcl procedure, then \fIcommand\fR will have access to the same
+local variables as code in the procedure.  This context may be
+different than the context in which the trace was created.
+If \fIcommand\fR invokes a procedure (which it normally does) then
+the procedure will have to use \fBupvar\fR or \fBuplevel\fR if it
+wishes to access the traced variable.
+Note also that \fIname1\fR may not necessarily be the same as the name
+used to set the trace on the variable;  differences can occur if
+the access is made through a variable defined with the \fBupvar\fR
+command.
+.LP
+For read and write traces, \fIcommand\fR can modify
+the variable to affect the result of the traced operation.
+If \fIcommand\fR modifies the value of a variable during a
+read or write trace, then the new value will be returned as the
+result of the traced operation.
+The return value from  \fIcommand\fR is ignored except that
+if it returns an error of any sort then the traced operation
+also returns an error with
+.VS
+the same error message returned by the trace command
+.VE
+(this mechanism can be used to implement read-only variables, for
+example).
+For write traces, \fIcommand\fR is invoked after the variable's
+value has been changed; it can write a new value into the variable
+to override the original value specified in the write operation.
+To implement read-only variables, \fIcommand\fR will have to restore
+the old value of the variable.
+.LP
+While \fIcommand\fR is executing during a read or write trace, traces
+on the variable are temporarily disabled.
+This means that reads and writes invoked by
+\fIcommand\fR will occur directly, without invoking \fIcommand\fR
+(or any other traces) again.
+.VS
+However, if \fIcommand\fR unsets the variable then unset traces
+will be invoked.
+.VE
+.LP
+When an unset trace is invoked, the variable has already been
+deleted:  it will appear to be undefined with no traces.
+If an unset occurs because of a procedure return, then the
+trace will be invoked in the variable context of the procedure
+being returned to:  the stack frame of the returning procedure
+will no longer exist.
+Traces are not disabled during unset traces, so if an unset trace
+command creates a new trace and accesses the variable, the
+trace will be invoked.
+.VS
+Any errors in unset traces are ignored.
+.VE
+.LP
+If there are multiple traces on a variable they are invoked
+in order of creation, most-recent first.
+If one trace returns an error, then no further traces are
+invoked for the variable.
+If an array element has a trace set, and there is also a trace
+set on the array as a whole, the trace on the overall array
+is invoked before the one on the element.
+.LP
+Once created, the trace remains in effect either until the
+trace is removed with the \fBtrace vdelete\fR command described
+below, until the variable is unset, or until the interpreter
+is deleted.
+Unsetting an element of array will remove any traces on that
+element, but will not remove traces on the overall array.
+.LP
+This command returns an empty string.
+.RE
+.TP
+\fBtrace vdelete \fIname ops command\fR
+If there is a trace set on variable \fIname\fR with the
+operations and command given by \fIops\fR and \fIcommand\fR,
+then the trace is removed, so that \fIcommand\fR will never
+again be invoked.
+Returns an empty string.
+.TP
+\fBtrace vinfo \fIname\fR
+Returns a list containing one element for each trace
+currently set on variable \fIname\fR.
+Each element of the list is itself a list containing two
+elements, which are the \fIops\fR and \fIcommand\fR associated
+with the trace.
+If \fIname\fR doesn't exist or doesn't have any traces set, then
+the result of the command will be an empty string.

+.SH NAME

+.SH SYNOPSIS
+\fBunknown \fIcmdName \fR?\fIarg arg ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command doesn't actually exist as part of Tcl, but Tcl will
+invoke it if it does exist.
+If the Tcl interpreter encounters a command name for which there
+is not a defined command, then Tcl checks for the existence of
+a command named \fBunknown\fR.
+If there is no such command, then the interpreter returns an
+error.
+If the \fBunknown\fR command exists, then it is invoked with
+arguments consisting of the fully-substituted name and arguments
+for the original non-existent command.
+The \fBunknown\fR command typically does things like searching

+\fBunset \fIname \fR?\fIname name ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command removes one or more variables.
+Each \fIname\fR is a variable name, specified in any of the
+ways acceptable to the \fBset\fR command.
+If a \fIname\fR refers to an element of an array then that
+element is removed without affecting the rest of the array.
+If a \fIname\fR consists of an array name with no parenthesized
+index, then the entire array is deleted.
+The \fBunset\fR command returns an empty string as result.
+An error occurs if any of the variables doesn't exist, and any variables
+after the non-existent one are not deleted.

+.SH NAME
+uplevel \- Execute a script in a different stack frame
+.SH SYNOPSIS
+\fBuplevel \fR?\fIlevel\fR?\fI arg \fR?\fIarg ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+All of the \fIarg\fR arguments are concatenated as if they had
+been passed to \fBconcat\fR; the result is then evaluated in the
+variable context indicated by \fIlevel\fR.  \fBUplevel\fR returns
+the result of that evaluation.
+.PP
+If \fIlevel\fR is an integer then
+it gives a distance (up the procedure calling stack) to move before
+executing the command.  If \fIlevel\fR consists of \fB#\fR followed by
+a number then the number gives an absolute level number.  If \fIlevel\fR
+is omitted then it defaults to \fB1\fR.  \fILevel\fR cannot be
+defaulted if the first \fIcommand\fR argument starts with a digit or \fB#\fR.
+.PP
+For example, suppose that procedure \fBa\fR was invoked
+from top-level, and that it called \fBb\fR, and that \fBb\fR called \fBc\fR.
+Suppose that \fBc\fR invokes the \fBuplevel\fR command.  If \fIlevel\fR
+is \fB1\fR or \fB#2\fR  or omitted, then the command will be executed
+in the variable context of \fBb\fR.  If \fIlevel\fR is \fB2\fR or \fB#1\fR
+then the command will be executed in the variable context of \fBa\fR.
+If \fIlevel\fR is \fB3\fR or \fB#0\fR then the command will be executed
+at top-level (only global variables will be visible).
+.PP
+The \fBuplevel\fR command causes the invoking procedure to disappear
+from the procedure calling stack while the command is being executed.
+In the above example, suppose \fBc\fR invokes the command
+.DS
+\fBuplevel 1 {set x 43; d}
+.DE
+where \fBd\fR is another Tcl procedure.  The \fBset\fR command will
+modify the variable \fBx\fR in \fBb\fR's context, and \fBd\fR will execute
+at level 3, as if called from \fBb\fR.  If it in turn executes
+the command
+.DS
+\fBuplevel {set x 42}
+.DE
+then the \fBset\fR command will modify the same variable \fBx\fR in \fBb\fR's
+context:  the procedure \fBc\fR does not appear to be on the call stack
+when \fBd\fR is executing.  The command ``\fBinfo level\fR'' may
+be used to obtain the level of the current procedure.
+.PP
+\fBUplevel\fR makes it possible to implement new control
+constructs as Tcl procedures (for example, \fBuplevel\fR could
+be used to implement the \fBwhile\fR construct as a Tcl procedure).

+.SH NAME
+upvar \- Create link to variable in a different stack frame
+.SH SYNOPSIS
+\fBupvar \fR?\fIlevel\fR? \fIotherVar myVar \fR?\fIotherVar myVar \fR...?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command arranges for one or more local variables in the current
+procedure to refer to variables in an enclosing procedure call or
+to global variables.
+\fILevel\fR may have any of the forms permitted for the \fBuplevel\fR
+command, and may be omitted if the first letter of the first \fIotherVar\fR
+isn't \fB#\fR or a digit (it defaults to \fB1\fR).
+For each \fIotherVar\fR argument, \fBupvar\fR makes the variable
+by that name in the procedure frame given by \fIlevel\fR (or at
+global level, if \fIlevel\fR is \fB#0\fR) accessible
+in the current procedure by the name given in the corresponding
+\fImyVar\fR argument.
+The variable named by \fIotherVar\fR need not exist at the time of the
+call;  it will be created the first time \fImyVar\fR is referenced, just like
+an ordinary variable.
+\fBUpvar\fR may only be invoked from within procedures.
+.VS
+\fIMyVar\fR may not refer to an element of an array, but \fIotherVar\fR
+may refer to an array element.
+.VE
+\fBUpvar\fR returns an empty string.
+.PP
+The \fBupvar\fR command simplifies the implementation of call-by-name
+procedure calling and also makes it easier to build new control constructs
+as Tcl procedures.
+For example, consider the following procedure:
+.DS
+.ta 1c 2c 3c
+\fBproc add2 name {
+    upvar $name x
+    set x [expr $x+2]
+}
+.DE
+\fBAdd2\fR is invoked with an argument giving the name of a variable,
+and it adds two to the value of that variable.
+Although \fBadd2\fR could have been implemented using \fBuplevel\fR
+instead of \fBupvar\fR, \fBupvar\fR makes it simpler for \fBadd2\fR
+to access the variable in the caller's procedure frame.
+.PP
+.VS
+If an upvar variable is unset (e.g. \fBx\fR in \fBadd2\fR above), the
+\fBunset\fR operation affects the variable it is linked to, not the
+upvar variable.  There is no way to unset an upvar variable except
+by exiting the procedure in which it is defined.  However, it is
+possible to retarget an upvar variable by executing another \fBupvar\fR
+command.

+.SH SYNOPSIS
+\fBwhile \fItest body
+.BE
+
+.SH DESCRIPTION
+.PP
+The \fIwhile\fR command evaluates \fItest\fR as an expression
+(in the same way that \fBexpr\fR evaluates its argument).
+The value of the expression must a proper boolean
+value; if it is a true value
+then \fIbody\fR is executed by passing it to the Tcl interpreter.
+Once \fIbody\fR has been executed then \fItest\fR is evaluated
+again, and the process repeats until eventually \fItest\fR
+evaluates to a false boolean value.  \fBContinue\fR
+commands may be executed inside \fIbody\fR to terminate the current
+iteration of the loop, and \fBbreak\fR
+commands may be executed inside \fIbody\fR to cause immediate
+termination of the \fBwhile\fR command.  The \fBwhile\fR command
+always returns an empty string.
