IPUSHEQ 255 3 0x20 0x21  !! Push integer condition
                         !! for equality

IPUSHNE 255 3 0x20 0x22  !! Push integer condition
                         !! for inequality

SAND                     !! Pop 2 previous conditions
                         !! perform AND with them and
                         !! push the result on the
