Regardless, the increase from 15 to 123 much thwarted the design of my hypothetical cautious programmer. Is the behavior of z/SO becoming more UNIXy? Time was when a programmer coded SPACE() he knew he was allowed that much and no more. Nowadays it's less determinate. -- gil ---------------------------------------------------------------------- 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
