1792
1793    Returns the complement of the passed conditional instruction.
1794
1795    We use the order of the different conditions, e.g.:
1796
1797    ICMD_IFEQ         153
1798    ICMD_IFNE         154
1799
1800    If the passed opcode is odd, we simply add 1 to get the complement.
1801    If the opcode is even, we subtract 1.
