I'm guessing that the use ; was something like use CompanyNameStuff; that pulls in Text::CSV_XS and ghod knows what else, but it got anonymized. The OP is too new to Perl to know what to replace it with.

Strict and warnings should be considered mandatory in any new code. Don't try to add them to old code unless you know what you are doing, because you will get a million error messages and you will freak out and say "I'm never using strict and warnings again," and you mustn't say that!
