If this were a problem that I had to solve, I would now contact IBM support
and tell them that in the second call to ffs the compiler always puts a
zero argument into the call argument list, although it should put the
result of the
32 bit right shift there. There is clear evidence for this from the
ASSEMBLER
resolution that you posted yesterday. This is a compiler bug IMHO. There
were
no differing opinions from others so far.
Kind regards

I think I see your problem. Try compiling with LANGLVL(LONGLONG).
