In summary, the procedure is available to be called from other programs. Commonly done in service programs and the genre. For example, if you have a subprocedure called CalcTheTotalSale and you EXPORTed that (and did the right binding) then you could use that in other programs. If the subprocedure is only used internally to the module from which it is created then you don't need to export it. As baby steps the first time I tried an old RPG/400 CALL on a subprocedure that was larger than 10 characters I was baffled. That's when I first used CALLB and now CALLP. http://publib.boulder.ibm.com/infocenter/iseries/v5r3/ic2924/books/c092508425.htm#HDRPEXPORT Rob Berendt
