>Those 3 APP_WHATEVER's look like they're supposed to be constants

Yeah, thats what I thought too (we had very similar posts), but I've never seen this before, I've never pulled apart that many frameworks.

Is it really that common? I hope not. For some reason, that technique irks me, it works:

#define coVar poVar
coVar = 'Test'
wait window poVar

but it could get completely unobvious in writing and debugging. And while I see how it could make components that float between frameworks that have different oApp object references, the level of sohpistication is silly. I doubt the objects would have the same PEMs making wether or not is could be referenced pointless.
