Uses Amstrad CPC, but other machines with similar terminal functions can do the job. (The BIOS calls will be different however.)
<lang z80>ld hl,&0603 ;6 = ROW, 3 = COLUMN
call &BB75 ;set text cursor according to HL
ld hl,Message
call PrintString
ret ;return to basic
Message:
byte "Hello",0
PrintString:
ld a,(hl) ;read a byte from the string
or a ;check equality to zero
ret z ;if equal to zero, we're done
call &BB5A ;print accumulator as an ascii char to screen
inc hl ;next char
jr PrintString</lang>
