Sme, but manageable. The article Safe REXX at <http://www.rexxla.org/Newsletter/9812safe.html> and <http://www.rexxla.org/Newsletter/9901safe.html";> has some tips on avoiding REXX pitfalls.

It's horribly inconsistent and unpleasant to use. The buffer HAS to be a passed by reference (variable) as it could break REXX string length limits or contain characters that REXX chokes on. I can't help but think that you've made a rod for your back. REXX is superficially simple but in my experience, which is 30 years of using the language, it is anything but and has endless pitfalls. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
