Huh? FrmGetObjectPtr() is the proper way to get a form
pointer? Well ... no. It's the proper way to get a pointer to
an object that lives in a given form.
I still don't see no GetObjectPtr() in the API docs. You
say it's in sample source code? Perhaps the sample
source code has (as I suggested) GetObjectPtr() as
a wrapper for something like:
FrmGetObjectPtr(FormGetFormPtr(), FrmGetObjectIndex(ID));
... but I'd have to see the code for GetObjectPtr(). It's
gotta be somewhere since it isn't part of the actual Palm API.
