You could count the index: { my $index = 0; foreach my $value ( @array ) { . . . $index++; } }
The outer braces keep $index to a smaller scope. BTW, $value above is an alias. If you are needing the index to change the current value in @array you can do it by changing $value.
I figured that's what it would probably come down to. I don't need the index for something in the array I'm working with but to access a related array with related data at the same indexes.
