When I took a look at objects.pas in the \test\borland_\ directory (a copy below), a few questions raise to mind. 1. Does the character c have to be desposed in the destructor? If so, is char (0) a null character? 2. If there are variables (character, arrays ,strings, etc) in a function in an object, do they have to be manually deleted? If so, how would I erase each one of them? 3. Is there such a thing as a pointer to a function?

Thanks Tom
