But if you use an index register instead of HL you could use an offset. Now the 8080 didn't have index registers, so this may have been an issue on these.
But the index registers are for weenies... ;-) one extra byte of opcode, and 12 T-states. Doing an INC (IX+1) takes the same time as INC HL; INC (HL); DEC HL. The only fun about the index registers was the load of undocumented instructions that allow manipulation of upper and lower byte separately....
