The tip e-mail you sent on Describe Select-Options may be useful. However, you would need to customize it for each select-option/parameter in program's selection screen. That is tedious, time consuming, and error prone.
Why not use a standard FM? This routine that I have written code can be dropped in to any program as is, no mods.
It shows only options with values, leaves out "no-display" selections, and has a pretty frame to boot!
