Re: Procedure pointers - can I do this??

Hi Larry,

As someone pointed out somewhere on this list, one of the advantages of
getter/setter procedures is that they can determine what they're going to
return, and in fact, even if they're going to return something.  Why not
simply have the getter procedure check to see who the caller is?  If it's a
service program, allow it, otherwise, fail.  Presumably you could have any
other criteria you like to decide whether to return the value to the caller
or to send an escape message or something to have it fail.
