Found the problem! Was Re: float does not parse '0.000000E+00'

Sun Jun 4 06:11:57 EDT 2000

I found the problem. It's related to lists; it seems to me that python
does not allow smoothly things like:
numbers = [n,m] =  map(int, numbers)

oops.. I tried catching the exceptions in that version. It wasn't the
one that fails on float.

Thanks for the tip!!!!

No. it runs smoothly.

LCASE.001 is the only file parsed.

...well... that's becuase I'm not a native english speaker and often I
misspell words... 8-)
