Here are a couple of attempts using just jump_i. I've played a bit
with the assembler locally to try to make it allow 'set I0, LABEL',
followed by 'jump I0', but I think it always calculates relatative
offsets for labels as needec by branch, et al. Do we need an
assembler syntax for 'absolute location of this label'?
I think jump.pasm should work (I've hardcoded the jump-to locations
as hex numbers), but it doesn't.
The jumpsub.pasm example is closer to what I'd really like to do...
Any thoughts?
Regards,
