Hi all,

I have a question about SetJmp/LongJmp. They don't care about FPU stack, so it remains what it was before call of LongJmp. Can one be sure that there is nothing in FPU stack when either SetJmp or LongJmp is called? Is it emptyed before a call of any subroutine or something like this?

Ingmar,
