But if this happens, it is bad coding. Programs do not need to use

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.
