in reply to multiple commands before unless ?

Or use the comma operator:

#!/usr/bin/perl
use strict;
use warnings;
use constant TRUE => 0;

printf("System Error\n"), exit unless TRUE;
print 'I should never be printed',"\n";

Update: Changed code so it follows question example code.

    I don't see how this applies. I wasn't trying to print a variable, but rather print a string and then exit the script. Am I missing something.
