you should also concetrate on more useful ROM call's like _getky or _getkey,
and such, I also suggest learning a little more asm before writing a tutorial...
here is quick program that will wait for enter to be pressed then exit:
init:
call _clrLCD			;clears lcd
call _runindicoff		;turns run indicator off
Start:					
call _getky			;get key ROM call
cp K_ENTER			;check for zero flag set on ENTER
jr z,Exit				;if it is jump to Exit
jr Start				;if not loop back to start
Exit:					
call _runindicon		;turns run indicator back on
ret						;end of program
