** Create an entry for the goto and the code for it. As it is not known ** at this point whether the goto may need a CLOSE, the code has a jump ** followed by an CLOSE. (As the CLOSE comes after the jump, it is a ** dead instruction; it works as a placeholder.) When the goto is closed ** against a label, if it needs a CLOSE, the two instructions swap ** positions, so that the CLOSE comes before th

** positions, so that the CLOSE comes before the jump.
