But if you have that kind of program, and a rough answer would suffice, do you really need to figure out the most efficient way of getting it? (Conversely, if you do want the most efficient way, doesn't that (perhaps) imply that you don't have that kind of program?) -- Walt ---------------------------------------------------------------------- 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
