Re: [Omaha.pm] Getopt::Long and opt_ variables



<quote from="http://www.perl.com/doc/manual/html/lib/Getopt/Long.html";>
Note that, if your code is running under the recommended use strict 'vars'
pragma, it may be helpful to declare these package variables via use vars
perhaps something like this:

  use vars qw/ $opt_size @opt_sizes $opt_bar /;
</quote>

so ... you just need to add,

use vars qw/ $opt_place /;

OR

remove the statement,

use strict;
