I'm using VFP 7.0

I swear I figured this out once, but I can't do it now.

How can I produce a list of PEMs identical to the PEMs listed in the Project Manager when I check "Non-Default Properties Only"?

I tried to use amembers( la, lo, 1, 'C' ), but that produces a list of all PEMs that have been changed from their baseclasses. I want just those PEMs that have been changed in this sub-class only.
