	I've been listening to the replies I got, and this is what to
do... When the asm code is being pasted in multiple times as a macro, the
label is defined more than once.  What you need to do is specifiy either
'b' (for back) or 'f' (for forward) directly after the label on the jump
( 0: ... jge 0b).  At first, I tried this with alpha-numeric labels, but
that doesn't work.  You need to use numeric labels when doing this.
