I eschew STACK with any command that provides STEM as an alternative. I'm phobic that a rogue subroutine will corrupt my stack, or even DESBUF. I applaud ADDRESS SYSCALL for relying on STEM, never (AFAIK?) STACK. STACK is a crude circumvention for overly restrictive variable scoping. CMS Piplines has YA chaotic circumvention. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
