• Click on "My Documents" in the start menu.
• In the C:\ drive, find the Perl folder.
• Make a subfolder called "bin".
• Use notepad to save a copy of the script you're modifying, with a .pl extension, in C:\Perl\bin.
• From the start menu, select "run".
• In the window that pops up, type "cmd". This will open up another window with a prompt.
• In this window, type "cd Perl\bin" to get to the folder with your script.
• To run the script, type "perl filename.pl" in the command window.
• Edit your script in textedit, save it, and test it again with "perl filename.pl".
• NB - any files you save on an LLC machine might be erased. Always back up your work on a floppy or by ftping it to your Dante account.
