You're right that the on-line help is a bit vague on this point. You can string multiple statements as long as they each end with a semicolon, with a comma separating the compound statement from the iteration specification. i.e. Do[ Print[x]; Print[x^2]; Print[x^3], {x, 1, 5}] Alternately, you can enclose the compound statement in braces, with a comma again indicating the iterator as here Do[ { Print[x] Print[x^2] Print[x^3] }, {x, 1, 5}] Hope that helps. AS PS: I can't tell you how much I resent no-spam manoevers that presume your time is more valuable than mine :) -------------------------------------------------- Atul Sharma MD, FRCP(C) Pediatric Nephrologist, McGill University/Montreal Children's Hospital <com3 at ix.netcom*NOSPAM*.com> wrote in message news:8elmvq$sii at smc.vnet.net... > Hello, > > I recently posted a question on 4/29/00 (msg # 22498) in which I > recieved emails addressing part 2 and part 3 of my question.
