UniVerse (and, I suspect but can't be certain about, UniData) functions are implemented as subroutines, with the first argument position on the stack reserved for the return value which is a DATUM. It can even be a file variable or subroutine variable! It follows that, while a subroutine can have 255 arguments, a function is only allowed 254. Don't go there! ------- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/ ______________________________________________________________________ This e-mail has been scanned by MCI Managed Email Content Service, using Skeptic(tm) technology powered by MessageLabs.
