That's the best part of the design.
But will z/OS (or its successor) ever attain the sophistication of Linux or Java which calculate the adjustment for a wide range of times and locales with no need for a semiannual update of control blocks? (This even works for Java under z/OS.) Then design of the TIME macro with its assumption that only two time zones matter is absurdly antiquated in this era of multinational operations. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
