I've written a Perl program that declares a hash at the top of the

better to pass the global hash by reference to each sub program to cut
down on possible typo errors or just leave it global and fix the problem
I have?


I think pass by reference would be the better way to go. It will
conserve memory as your not passing all the data around and it will
ultimately make maintenance easier.

Good luck,
