A specific program is selected from the general category represented
by the subform by clicking on the desired button in the \fIguide pane\fP
on the left of the subform.
This brings up a corresponding \fIpane\fP to the right of the subform for the
setting of appropriate required and optional parameters for that program.  
The subform may then be \fIglyphed\fP for use in a flow graph or 
executed directly using the `Execute' or `Run' button.
