Re: Using getopt

Your lexical 'my $opt_i' is masking the package $opt_i that Getopt::Std creates.

Use

use Getopt::Std;
use strict;

use vars qw/$opt_i/;
getopt('i');

print "Increment value is $opt_i\n";

Thanks for the replies. That works for me now. This is getting off the subject, but what exactly is the difference between `'my $opt_i'` and the `use vars` way? And could you point me to where I can read about 'lexical scope' and 'packages'? Thanks again.	[reply] [d/l] [select]

Dominus has an excellent article called Coping with Scoping that should help you out. Chapter 5 of the Camel and chapter 6 of the Panther are also relevant. `-- :wq`	[reply]
