Yes, I tried it. What I found out was that after it came to the correct

Here's the original:

AHUNDS:
  MOV A, R0
  FZERO:
	CJNE A, #0, FONE
	MOV R3, #ZERO
  FONE:
    CJNE A, #1, FTWO
	MOV R3, #ONE
  FTWO:
	MOV R3, #TWO

RET

 

oaky, let's say it goes into FZERO, and matches #0. it does the next instruction (MOV R3, #ZERO), and then goes to (FONE). since it doesn;t match, it proceeds to (FTWO), where R3 -which originally had #ZERO- gets overwritten by #TWO.

Did I get it right?

So that's why it's important to do a RET right after R3 is written so it won't be rewritten by the last value.

Tell me if my explanation was wrong. Thanks for the idea, by the way.
