Clearly busted.  probably should be 0 (zero) without the J

I'm not sure I remember the code very well, but that should likely be an & for a
"multiple return" statement in MATCH.  IE a "return" returns to the line after
the call, while a return 1 returns to the first statement label passed as an
argument.

But, as I said previously, this is all broken and much code is missing.  IE look
at the last line of code, which must be "END" but isn't...
