Thank you, Matias, for your reply. I tried out your script, but I get the 
following error when using it:

jorg@blaubaer:~/test$ ./datenumkehr.py jo-001.asc 
Traceback (most recent call last):
  File "./datenumkehr.py", line 14, in ?
    if float(numbers[i])>=0:
ValueError: empty string for float()

As I never learned python (nor an other scripting language), I don't know 
what that means, nor how to fix it.
Any idea?
