Here're the steps I'd take:

1. Get rid of all the comments.
2. Run it to make sure I didn't break anything
3. Put a newline after every single semi-colon
4. Run it to make sure I didn't break anything
5. Start to fix the logic, renaming variables and the like
6. Run it after every single edit, to make sure I didn't break anything
7. Start getting rid of filler-code.
8. Run it after every single edit, to make sure I didn't break anything

A few tricks to keep in mind:

• *)=5; is a way of making a variable named $* and setting it equal to 5.
• Order of operations is critical.
• Delimiters don't have to be slashes.

That should be enough to get you started.
