( #3333=superdoc: print w/ replies, xml ) Need Help??

Hello.

I'm trying to use an option with an optional value and then test whether the option was used and if so whether an optional value was used with it; here's what I have:

use strict; use warnings; my $foo = undef; GetOptions( 'foo:s' => \$foo, ); my $sn = $ARGV[0]; if ($foo and $foo ne undef) { print "foo option used with optional value: $foo \n"; } elsif ($foo) { print "foo option used with no optional value \n"; } else { print "foo option not used at all \n"; }

That doesn't work, but hopefully it better illustrates what I'm trying to do.

Any help would be greatly appreciated.
