L32: Good question why I did that... no clue, really. It works, though, for my purposes. %%* is probably correct, and I will revise this.

L34-35: Google says otherwise: http://www.instructables.com/id/Slightly-More-Advanced-Basic-Batch/step2/ECHO-OFFON-Command/
That being said, I did test this both with and without the @echo off line... and it only worked with the @echo off line. At least on my systems (2 win xp, 1 win 7 64).

L21: It was complaining on my WinXP boxes, but that could be a security setting. Both of my WinXP boxes are the property of my employer, and they have some pretty crazy security protocols in place. Not sure if that has anything to do with it, but my WinXP boxes didn't like the extra slash at all.
