I am using VI on a unix box using Perl 5.x.... I thought there were a means of displaying the line numbers in your code. Maybe this is not a perl question at all. I do apologize but sincerely appreciate the responses.
Thanks,
In addition to the responses that you've already received, if you use vi to edit, then you should use the '+n' argument from the command line to put you directly to that line of the source file. Alternatively, while inside vi, type ':n' to go to line n in the file.
And no, that wasn't a Perl question. The next time you have a vi question, read the man page or buy the O'Reilly book.
