Sorry, I should have said. I'm writing a program to find prime numbers, and what I want it to do is go from 0 to 200 and divide each number by all other numbers. So I want say, 50 to be divided by 1 to 50, but to stop when it finds a modulus. If it were a prime number, it would be divided by everything between 1 and itself, and no modulus would be found. Any suggestions?

Specifically, That's part of the Perl 7 - DWIM spec. You may have to wait until easter though.

Once you find one, you change the rules and are now looking for a number who's modulus 3 is zero, then 4 etc? my $mymod = 2; for my $num ( @numarray ) { if( $num % $mymod == 0 ) { $mymod ++; <do something here with $num> } } Hope that helps.
