You have no choice with pointers.

My 86' assembler is very rusty, I worked more with the 68000. IIRC,
you could do "short jumps", in which the destination address was
relative to the current program counter.

I never remember what model Linux uses, but don't we have short
jumps?

The flat memory model. Segment registers aren't used anymore,
although FS and GS may still be used.

Then, no short or relative jumps? Say "jmp +125"?


Well, there are no near jumps, those are relative to CS, which isn't
used. There are relative jumps, with either 8bit or 32bit
displacement.
