You could but why. As part of your print you could do somehting like:
my $MyId = 1;
foreach $file (@files) {
printf "%3d $file\n", $MyId++;
}
Which should print out just as you want.
Now the individual can enter say 3, and you can put from @files by subtracting 1 and
you would have the file. Using scalar(@files) you now have your Max files within your
array, so if they enter 6. You subtract 1 and get 5 but scalar(@files) returns 4, you
know they entered an invalid number.
Just a thought.
Wags ;)
