If you've got something that big... (1) Reduce the number of globals. If you have "many", there's something wrong that could be improved with better design. If your script isn't object-oriented, it probably should be. (2) Use a naming convention for globals, like $ALL_CAPS, or @Initial_cap that you don't use for any other variables. -- Peter Scott Pacific Systems Design Technologies http://www.perldebugged.com/ -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
