PrintString:

ld a,(hl) ;HL is our pointer to the string we want to print
|
|
cp 0 ;it's better to use OR A to compare A to zero, but for demonstration purposes this is easier to read.
|
|
ret z ;return if accumulator = zero
|
|
call PrintChar ;prints accumulator's ascii code to screen - on Amstrad CPC for example this label points to memory address &BB5A
|
|
inc hl ;next char
|
|
jr PrintString ;jump back to the start of the loop. RET Z is our only exit.
