DESCRIPTION
Normally when a task terminates the values of the task parameters used
are stored for the next invocation of the task in a disk file in the
users UPARM directory.  However if the task parameters have been
cached by the \fIcache\fR command, this will not be done until the
CL terminates.  In the case of a background job, automatic updating of
parameters is disabled.  The \fIupdate\fR command is used to force the
parameters for a task to be updated on disk.

EXAMPLE
1. Update the parameters for the \fIpage\fR task.

	cl> update page

BUGS
The parameter set is only updated on disk if a parameter has been modified
since the last update.
