Bill, My advice is that the small amount of extra pain involved in putting your common code into a real external subroutine is always worth it in the end. I'm a great believer in INCLUDEs, but only after an extreme amount of thought will I put significant logic in them. If processing is necessary it should nearly always be done in the main program, or if needed in more than one place then in an external subroutine that you CALL. You chances of stuffing up a program that INCLUDEs logic by a small change to that logic are much higher than if you CALL it as an external routine. Immediately you eliminate the risk of someone introducing a new local variable into either your main line or the INLCUDE and finding that it collides with something else which was also supposed to be local. That's my 5c. YMMV Cheers, Ken ------- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
