Ok I will have a second go when using perl -d with action X (V) cause the following error. You can't FIRSTKEY with the %~ hash at /home/kevin/perl5/perlbrew/perls/perl-5.15.7/lib/5.15.7/dumpvar.pl line 382 ...propagated at /home/kevin/perl5/perlbrew/perls/perl-5.15.7/lib/5.15.7/perl5db.pl line 2471. at /home/kevin/perl5/perlbrew/perls/perl-5.15.7/lib/5.15.7/perl5db.pl line 2471 DB::DB called at sewi.pl line 23 Debugged program terminated. Use q to quit or R to restart, use o inhibit_exit to avoid stopping after program termination, h q, h R or h o to get additional info. So I have attached a patch to fix this. Can somebody please apply this. regards bowtie for more info read perl5db -> You can't FIRSTKEY with the %~ hashThread Next
