Is there a better way of dividing a signed 1-byte integer
by 2 than this? (which says, if var is positive, just do LSR,
otherwise LSR and OR w/ -128 i.e. #%10000000 ) It just seems odd
to have to branch to preserve the sign bit but I wasn't clever
enough to come up with a better way...
LDA var
BPL posval
negval
LSR
ORA #-128
JMP done
posval
LSR
done
STA var
