Re: Specifiying a Range for Variables?

Here's one way.

$cmd1 = 'This';
$cmd2 = 'Is';
$cmd3 = 'a';
$cmd4 = 'test';
 
my @cmds = map {${"cmd$_"}} (1..4);
 
for (@cmds){
  print "$_\n";
}

I'll refrain from the obligatory "You should use a hash instead..." statement on the assumption that this is simply a learning exercise. :)
