Call_Procedure, Call_Method, and Call_Function, along
with Execute, I call "virtual" functions. With Execute
you create the actual IDL command you want to execute
as a string. With the other three virtual functions
the name of the procedure/function/method is passed
as a string (usually so it can be determined at run-time)
but the rest of the parameters are passed normally,
as if to the correct procedure/function/method.

Cheers,

David
