You're missing package SS::ExportScalar;, so the script never imports DEBUG, so DEBUG is not declared in the script, so it's a bareword, so strict throws an exception.

    Sorry, must have got garbled in the transfer to the website. See the whole thing below. Note that if this was the case, the script would not have run the second time after changing strict and execution would be aborted at compilation because Perl wouldn't find ExportScalar.

    type ExportScalar.pm
package ExportScalar;
use strict;
use warnings;
use Exporter;
our @ISA = qw( Exporter );
our @EXPORT_OK = qw( DEBUG );

our $DEBUG = 1;

sub DEBUG {
   if (@_) { $DEBUG = shift; }
   return $DEBUG;
}
1;

      Ooooooops, my bad! It has to be 'package SS::ExportScalar' instead of just 'package ExportScalar'! Thank you so much! My NPR donation will be diverted to the Perl Monks! ;o)
