on the CRTCMD command, look at the HLPPNLGRP parameter. Look to the IBM infocenter for information how to create a panel group.
This is described in the <a href=”http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=/rzahg/rzahgapdlprint.htm”>Application Display Programming .PDF</a> manual. Topic to read is ‘Assigning Panel Groups as Help for Commands’ in Chapter 20. Examples are included.
Almost all UIM panel specifications are in that manual.
