[HP41] mcode question polling point entries
Hi mcode guru's,

I am struggling with some mcode using the HP41 polling entries, and I am probably messing up some registers. Is there any definition which CPU registers can be freely used and which must be restored during any of these polling entries?
Regards, Meindert
