Hi Carlos,
Well, I have not looked into this recently, but in the past I determined
that all you could do was set an improbable value, read, and see if it
changed. If you REALLY wanted to know, you would have to do this twice,
with two improbable values. I guess it is possible that fortran 2003 has a
spec that would cover this, but I would not bet on it; I don't currently
have any specs past 1995. This IS a really stupid feature of fortran, at
least through 1995, but it is not like it is the only stupid feature of
fortran :-) I would be overjoyed if someone with experience with 2003 could
say wrong, wrong, wrong. Scott? Joe Krahn? We could write our own code,
but it would involve parsing namelists I would think...
Regards - Bob
