Yes, if the job says do not repeat values, this will fit. But this is *not* a random distribution. You get unique numbers for each run, just in a random order. True randomness is supposed to repeat values. If your program plays Roulette, I'd like to be the 37th player :) Peter ------------------------------------------------------------- Brought to you by CommuniGate Pro - The Buzz Word Compliant Messaging Server.
