What needs to change can depend upon what is in "bunch_of_constants.pl". If, in that script, you've declared your variables with "my", then you will not be able to easily get at them. You can create a wrapper subroutine that returns them, however. If they are truly package variables, though, then you determine the package that they're in and you put the dollar sign at the front of the variable name (assuming, in this case, that they're in the "main" package): $main::one_constant However, I would urge you to turn "bunch_of_constants.pl" into a proper module and using Exporter.
