Sorry, George, but I can't accept this as a good reason to define all classes in PRGs and give up using the class designer. I don't think it worths it.

>One reason is that the memory required for PRGs is significantly less than VCXs. This is something that I had heard, but never tested until now. I created a simple class with one custom property and one custom method. Using SYS(1016), I measured how much memory was used by these objects. The PRG used approximately 11K less than the VCX. I test this twice, re-starting VFP each time with the same results.
