I am trying to have the choice of live in this game be 1-9.  I can't figure
out what is wrong with the code.  Instead of stopping at 1 or 9 it keeps going
down.  What is wrong?  Thanks

Greg Sharp
Here's my code:
Options:
 ld (Lives),a
 call CLEARLCD
 ld hl,0
 ld ($800C),hl

 ld hl,&Programmer

 call GET_KEY
 cp K_PLUS
