in reply to Getopt::Long and default number


I think you want the ":" signifier when identifying your options. This says the value for the option is optional. If the option is present without a value, it takes the number indicatied after the ":" ; otherwise it takes the user-supplied value. This is in the POD in the section "Summary of Option Specifications"

use Getopt::Long; my $opt = 0; GetOptions ("opt:100" => \$opt ); print "Opt is:\t$opt\n";
My test runs give:
> --opt Opt is: 100 > --opt 7 Opt is: 7 > Opt is: 0
