Perhaps that's what I did (processing the command line parameter). For 
some reason it works now.

I was referring to the user launching my script with a filename as 
parameter:

test.py c:\test.txt

Here's my code so far (it removes blank lines from the input file (for 
example c:\test.txt), and creates a new file (c:\test_new.txt) to store 
the output):

import string
import sys
import os
if len(sys.argv)<=1:
     print 'Usage: dbl.py [filename]'
     sys.exit()
b1=sys.argv[1]
b2=b1[:-4] + '_new' + b1[-4:]
f1=open(b1,'r')
f2=open(b2,'w')
r1=f1.readlines()
for r in r1:
     if string.capwords(r)<>'':
         f2.write(r)
f1.close()
f2.close()
print 'Output file: ' + b2
os.system ('start notepad.exe ' + b2)
