I want to pull a group of random numbers within a certain range, but
don't want to check after each grab whether I've previously pulled the

between 1 and 100. I'll store the numbers in an array. Can I do this
without having to search through the array each time I generate a new
number to ensure I haven't already pulled the number?
Thanks in advance.
As Steve says, that's not really a random selection; it's a random *ordering*
("select without replacement" in statistics jargon. You can get the effect by
having a table of your random numbers and shuffling it, sorting the records by
a random value. You can store them in a table and have some field (yes/no
perhaps) indicating which ones you've already selected.
