Thanks for the tip. This works. As you can tell I don't have much experience
with C,
so simple things can cause big trouble.

Tried "ddd...d" with an without ( ). No success.
But the loop with the array works (see above) and this just what I want.

I am writing my program in Python (it's a water quality model). There is a
"main" model written by somebody else in FORTRAN which calls  submodels as
DLLs. My Python model is one of these submodels. Now I try to speeze
everything into a DLL. So C is the "glue" and just has to pass some args
back and force from the main to the submodel. I do NOT program any
functionallity in C (just the argument passing via the DLL). Besides this it
seems I need to improve my knowledge of C.

Thanks for your help.
