Thanks for the reference. I tried it with a general example and got it
to work - I used an index that counts up to a threshold that is set to
break. It does not work though with my real code. I suspect this is
because I cannot really read any lines from an empty file, so the code
gets stuck even before I get to j=j+1:
line = f.readline()[:-1]
j=0
while 'PRIMARY' not in line:
line = f.readline()[:-1]
j=j+1
if j==30:
break
Any suggestions?

somehow. I use 'while 'word' not in line' to recognize words in the

1) how do I overcome this, and make the script skip the empty files?
(should I use another command?)
2) how do I interrupt the code without closing Python? (I have ActivePython)
Try the docs first. You need to read about 'continue' and
'break' statements: http://docs.python.org/tut/node6.html
HTH.
