Not sure of your system but most editors have some sort of "find lines" functionality. If you are on a Windows PC most often CTRL+G will bring up a prompt to jump to the line. Even in "notepad" on Windows CTRL-G works. Personally as an editor in Windows I use UltraEdit32. Its like a text editor on steriods. I'm pertty sure also on Unix systems "vim" has the option to display lines numbers and also an option to jump to line numbers. Conversely try running the perl debugger "perl -d <scriptname>" and type "h" for help. From here you can move through your program in live mode line by line and see your variables as you go. Enjoy!
