I wouldn't say that it was "Blatantly untrue". However, I did neglect to include my normal qualification instructing the person to always use the strict and warnings pragmas like I did in the optional method that I posted. With the inclusion of the strict pragma, then the use of 'our' in Script.pl would be needed. The OP didn't show us the shebang for the Script.pl, but since the -w switch is being used in Config.pl, it's a fair assumption that it's being used in Script.pl. Assuming that to be true, failing to use 'our' in Script.pl will generate the following warning.
