A trick I used to use was variable abstraction (holding the name of a vairable inside of a variable). For example I have a set of arrays @a, @b and @c. I have another variable which holds the name of the array I was to look at, say $x. I would set $x to 'b' and then have the array I wanted as @$x.

#!/usr/bin/perl

@a = (1, 2, 3);
@b = (4, 5, 6);
@c = (7, 8, 9);
$x = 'b';

print "@$x\n";

Now, this won't work if you use strict in your program.

My question is, what is the correct way of doing this?

Thanks!
