+DESCRIPTION
+\fIChdir\fR is used to change the current working directory.
+When called without any arguments, \fIchdir\fR sets the default directory
+to "home$", the users home directory.
+The new directory can be specified as an IRAF logical name,
+as a sub-directory of the current directory,
+as a path from either a logical directory or the current directory,
+or as an operating system dependent name.
+
+The names \fIchdir\fR and \fIcd\fR are synonyms.  Note that the command
+\fIback\fR may be called after a \fIchdir\fR to return to the previous
+directory without typing its name.
+.ih
+EXAMPLES

+	cl> cd dataio
+
+4. From "dataio", go back up to "pkg" and down into "images".

+
+5. Go to the "tv" directory, a subdirectory of "images", regardless of the

+and go there.  Note that the character $ is not permitted in host file or
+directory names.
