Hi Sergey,
Thanks very much for the suggestion.
Position 4 of the array appears to give the classlib that the form is in, but I don't see the app anywhere. The documentation is unclear, but what I see when I run this is:

1. if the current program is a form, then positions 4 and 2 contain the classlib
2. if the current program is a prg, then position 4 contains the program and position 2 contains the app.

Can you confirm this?
Do you think there is any way to get the app for a form?

Thanks, Chaim
