Thanks for pointing out that I was "not setting $over anywhere", the code snippet
below clears that up.
#!/usr/bin/perl -w
use strict;
#this program's specification is on page 167
#in the Llama book under exercise 1
my ($source, $go, $dest, $expression, $over);
$over = 1 if($ARGV[0] eq "-o");
until($go){
print "Please enter a source filename: ";
chomp ($source = <STDIN>);
$go = $over ? 1 : &filep($source, 0);
}
$go = 0;
until($go){
print "\nPlease enter a destination filename: ";
chomp ($dest = <STDIN>);
$go = $over ? 1 : &filep($dest, 1);
}
Since you asked:

First, the commented out line about the Llama was actually in there for myself (to
remind me where I got the idea from). Second, the '-o' option is just a safety
over-ride flag I put in to show get avound some of my program's more irritating
features, like not being able to make a new file.
Lastly, I thought that the "<something> ? <true_expression> : <false_expression>"
conditional operator was called a 'conditional hook', I could be wrong, though.
Thanks for your help,
