Sorry that was a typo... I meant 5.8.3. Having another Perl installation will sure solve the problem but its a long shot to get a new version of Perl installed in the live production system, especially just for one program. The Sysadmins are suggesting that we use the existing perl Installations. The job scheduler is very flexible so I am not so concerned about running a program with new settings on it, but the only thing that is pressing is the perl Installation. I guess I will give the AIX perl installation a shot.. Thanks for your help!
