PD.S null selection

[DonQuixote]

I used PD.S to build a selection for intuitive help.  The selection screen pops-up even if zero items are selected and the only way out if F10 (cancel); which takes me back to the calling screen.  But then, nothing works.  Even though I see the screen, SB thinks its one level up.  Any ideas how to stop the selection screen from popping-up if no items are selected?

That certainly doesn't sound like normal behavior.  What options are you using on the /PD.S?

the options are  (MSTB   but it is important to note that the SSELECT prompts for input (e.g.  WITH DATE > "?I")
