OK, I've tried several different things to get this code to work, but I guess 
something is required that I'm unaware of.  The code works fine if I don't 
mess with the variable (friction), and I've tried putting that section in 
several parts of the code, still no luck. It just freezes when I hit 2nd.  
I'm sure it's something easy...

getkey_2nd:
      ld   a,kReset     
    out  (1),A      
    ld   a,Group7       
    out  (1),A      
    in   a,(1)  
    cp k2nd 
    ret nz
    pop hl
    pop bc
    inc b
    push bc
    push hl
    ld hl,(friction)
    inc hl
    inc hl
    inc hl
    ld (friction),hl
    ret

Also, could I use "add hl,3" or something similar instead of incrementing 
multiple times?
Any help is appreciated.
