Spooky has asked for the wisdom of the Perl Monks concerning the following question:

I'm getting "Integer overflow" errors out of my Perl code. The message produces a line number associated with the source code which makes sense but it also refers to a line number from the input file. My problem is the input file being in a binary format - which is really ugly and only made more understandable when I turn "hexl mode" on in emacs. Is there a way to output the input file line the code is choking on?

    $. : Each filehandle in Perl counts the number of lines that have been read from it. (Depending on the value of $/ , Perl's idea of what constitutes a line may not match yours.)

    If your input is a binary file, why are you reading it line-by-line?
