Well, Agony 3.1 uses the same principle and actually goes one step further: Charon v8.1 needs a <2667 in the B-field of its SPL/JMP bomb to muck up imps, whereas Agony clobbers them with a straight SPL 0,0 carpet (code soon). >For anyone who doesn't have a copy of Charon v7.0: > [..] > djn scan,<-5 ;mutagenize/distract/count-down to clear This must be an early test version of Paul's (which doesn't work BTW). The real Charon v7.0 has djn scan,
