Well, here is a snip from my FLEX, my BISON and my
C-file...
Let me tell that all code comes trhough the compiler
correctly, and that the problems I get are at runtime.
So don't come with something like: "Is that variable
set?"
I hope someone can tell me what's wrong now...
If there is not sufficient code to locate the problem,
I can put some more code up...
