In gratitude to the monks who have helped me in the past I wanted to add...
I had the command line working on my Windows 7 machine and then had to re-image the hard drive for reasons I can't explain. After the re-image, the command line parameters would not work despite the assoc, ftype, and PATHEXT all being correctly set. After a frustrating day, I just started cruising the registry and found another entry for perl under HKEY_USERS\S-1-blah-blah-blah-Classes\pl_auto_file\shell\open\command. I added the %* and viola! ITS ALIVE!. Not sure why the new instance, but just wanted to throw out there for other frustrated monks.
