Thanks for your reply.
Up to now, I have not used 'use strict' for the very reasons you cite. Besides that, it appears to slow the script down tremendously (this may be due to the warnings). After I'm done with 'use strict', I am considering commenting the line so the script will load quickly again.
The script has a difficult to find intermittent defect. So, I'm employing 'use strict' to help find bad habits and maybe even help find this or some other defects.
I'm a C++ programmer by trade and because of the nature of C++, I try to let the C++ compiler find defects for me as often as possible. In this instance, I'm employing the same approach to Perl.
