You also need to look at the cycle count for the different ways of doing it (the first two ways…) to see which is really the most efficient time wise (if you care).

Fist approach: 4 bytes; 20 t-states. Second approach: 7 bytes; 32 t-states, but does not trash HL. Turbo Pascal's approach: 15 bytes; lots of t-states.

Ya, the Turbo Pascal method is pathetic...

Why a Z80? The last time a wrote code for a Z80 was in the late 70's...
