Description
Documentation says:
deflabel addr [name]
...
A little bit of caution is necessary here; if the same deflabel is used for different values, the last one wins and is used for the EQU statement.
What I'm seeing is that the last one is not winning, it's getting ignored, as evidenced below. I think it works fine, it's just the documentation that is wrong.
Using
deflabel 37A3 SCREEN_WIDTH_PIXELS
deflabel 37A8 SCREEN_WIDTH_PIXELS
results in
SCREEN_WIDTH_PIXELS equ $B8
cmp #SCREEN_WIDTH_PIXELS ; 37A2: C9 B8
bcc No_X_Wrap ; 37A4: 90 03
sec ; 37A6: 38
sbc #SCREEN_WIDTH_PIXELS ; 37A7: E9 B8
Using the address wrong for the second instance
deflabel 37A3 SCREEN_WIDTH_PIXELS
deflabel 37A7 SCREEN_WIDTH_PIXELS
results in
SCREEN_WIDTH_PIXELS equ $B8
cmp #SCREEN_WIDTH_PIXELS ; 37A2: C9 B8
bcc No_X_Wrap ; 37A4: 90 03
sec ; 37A6: 38
sbc #$B8 ; 37A7: E9 B8
