[fluka-discuss]: Unable to change beam direction directly in source.f

Dear Fluka users

I'm having trouble changing the beam direction using
TXFLK (NPFLKA)
TYFLK (NPFLKA)
TZFLK (NPFLKA)
in the source routine.

If I have the source routine read the directions from BEAMPOS card in Fluka
using e,g TXFLK (NPFLKA) = UBEAM, it works perfectly.
But if I try to define TXFLK (NPFLKA) as for example -1 directly in the
routine, nothing happens. With nothing, I mean that the beam misses my
target.

I've tried
TXFLK (NPFLKA) = -1
TXFLK (NPFLKA) = -1.0
TXFLK (NPFLKA) = -ONEONE
in hope that it should make any difference, but unfortunately not. I've
also tried to remove the BEAMPOS card completely in Fluka, but the same
results were achieved.
Any suggestions?

Thank you.

Best regards,
