Some code in .APP calls function(s) that exist only in the .EXE (simply because the .EXE and .APP share some class libraries). So when I compile/build the .APP I get a bunch of Unknow FunctionName - Undefined messages. But I have not seen error messages at run time. Does it mean that at run time when the code in the .APP calls one of the "unknown" functions they fire from the main .EXE?

>>First, thank you. But how do you create procedure and function headings? I am thinking that if I create a "dummy" procedure/function of the same name, at run time, these "dummy" procedure will be called. Do you see what confuses me?

I got it. Thank you.
