in reply to Trouble Creating a Menu

Your script works for me. Maybe the addition of a bit of code will help you see what is happening at the end of the script. You need to remember that STDIN is line buffered, so if you select 2 for example, you still need to hit a Return for it to be read by $question = <STDIN>;

If you want single key responses, see Re: Using File::Tail::select with STDIN? , where you don't need the Return key to capture a keystroke.

#!/usr/bin/perl -w use strict; my $question; my $computer; my @pc = qw(comp1 comp2 comp3 comp4 comp5); # Find out which computer to cold start system("clear"); do { print "Which computer would you like to cold start?\n"; print "1 - comp1 2 - comp2 3 - comp3 4 - comp4 5 - comp5\n"; $question = <STDIN>; chomp($question); } until ($question >= 1) & ($question <= 5); $question--; $computer = $pc[$question]; print "$computer\n"; print "Hit Return to continue\n"; <>; # wait for a newline

I'm not really a human, but I play one on earth.
