in reply to problem with loop

Or this:

use warnings; use strict; my @p = qw[PA5098 PA5100 PA5092 PA3175]; for my $i ( 0 .. $#p ) { last if $i == $#p; for my $j ( 0 .. $#p ) { print join( " " => ( $p[$i], $p[$j], $j - $i ) ), $/ unless $i + >= $j; } }
Output
PA5098 PA5100 1 PA5098 PA5092 2 PA5098 PA3175 3 PA5100 PA5092 1 PA5100 PA3175 2 PA5092 PA3175 1
I kind of like AnomalousMonk solution, because it has no help from ifs and unless. McA solution is also cool for me, but I don't like C-for loop in perl! :)

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
