OutputM oo+

<outputs oo..oo+7> AND X = Y AND X; X=Z; Y=T; Z=T

Updates up to 8 outputs (from output oo through output oo+7) at once according to the bits patterns in X and Y.

Y = the bit pattern to output. Ones and zeros will be output based on the mask in X.
X = the mask of outputs to change. Only outputs whose bits are one will change based on Y.

For example:


   LoadX  %00001101   ;we want 3=on 2=on 1=off 0=on
   LoadX  %00001111   ;only alter the first 4 outputs
   OutputM 6          ;change the outputs, starting from output 6.  So 9=on, 8=on, 7=off, 6=on (no other outputs affected)

OutputM pops the stack twice (removing both X and Y)

The address argument will be jndexed when executed inside a MultiTrack task and will be indexed if the instruction is preceded by the IasJ: precode.

Dialect restriction. OutputM is implemented only in dialects 6 or later.
