Hi,

Sorry for the late response, I tried all of the the suggestions, 
including correcting my typo of print sys[1:] and tried print 
sys,argv[1:], this does now work as long as I run 'python test.py fred 
joe' it returns all the arguments. If I try just test.py all I get is 
'[]' . Is there something wrong with my environmental variables in 
Windows XP, I would like to be able to just use the file name rather 
than having to type python each time. Any help would be gratefully received.
