It doesn't mean what it says. They should have used the word "may" instead of "must". It's simply a matter of convenience. You can write a constant how you like, and more than once. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
