Hey There,
Are you having problems modifying a variable you declare outside of the loop?
This code will increment the variable in the foreach loop and change it's value outside the loop.
Let me know if I'm misunderstanding you
Best Wishes,
Mike
I called it "poil" and this is the output below

#!/usr/bin/perl
$fancy=0;
print "BEFORE $fancy\n";
@loop = qw(1 2 3 4 5 6 7);
foreach $loop (@loop) {
$fancy++;
}
print "AFTER $fancy\n";I called it "poil" and this is the output below
-bash-3.2$ ./poil
