By all means, use a label! The assembler will let you know (give you an
error message) if you branch too far...
        Reminds me of back when I first started programming the old MC6800. I
didn't have an assembler, so I coded it by hand in hex. I got real good
at counting forwards and backwards in hex... I'd just start with 0 at the
beginning of the next instruction, then count FF, FE, FD, FC, etc. back
through the code until I got to where I wanted to branch to...
