NAME
lparam -- list the parameters of a task or pset
.ih
USAGE
lparam pset [pset ...]
.ih
PARAMETERS
.ls pset
The name of the parameter set to be listed.
.le
.ih
DESCRIPTION
\fILparam\fR lists one or more parameter sets. Psets are specified either by
the name of the task with which the pset is associated, or by filename (pset
files have the ".par" extension). If a file type pset is listed the extension
must be included, since it is the presence or absence of the filename
extension which \fBlparam\fR uses to distinguish between task-psets and named
(file) psets.
Each parameter is listed on a single line with the following format:
param = value prompt string
Here "param" is the name of the parameter, "value" is the current value of
the parameter (blank if undefined), and "prompt string" is the prompt for
the parameter, if any. If the parameter is hidden, then the line is enclosed
in parentheses. For arrays, instead of the values, a list of the
dimensionalities is given. The \fIeparam\fR task may be used to examine
or edit the contents of an array. When more than one task is listed the
task name is prefixed to the list of each tasks parameters.
.ih
EXAMPLES
1. List the parameter for the task \fIdelete\fR. Note that the positional
parameters are listed first, in the order in which they must be specified
on the command line, followed by the hidden parameters.
.nf
cl> lparam delete
files = "temp" list of files to be deleted
go_ahead = yes ?
(verify = no) verify operation before deleting each file?
(default_acti = yes) default delete action for verify query
(allversions = yes) delete all versions of each file
(subfiles = yes) delete any subfiles of each file
(mode = "ql")
.fi
2. List the contents of the file pset "delete.par". Named psets such as this
are most commonly produced using the \fB":w filename"\fR colon command in
\fBeparam\fR, e.g., to prepare several different versions of the parameter
set for a task.
cl> lparam delete.par
.ih
BUGS
You cannot list the parameters of a task that does not have a parameter
file (e.g., all builtin tasks).
