In response to other postings, TRUNC(OPT) should work as well as TRUNC(|BIN) without the brain dead code generation if all operands are either binary or literals. The more interesting question is why use a pointer when reference modification works well for playing with the SMF30 records? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
