How can I code diodes? I am doing them for two new conductors, PCON and NCON. I am trying to make a diode of METL and PCON. PCON > METL but METL !> PCON.

1) You are not a coder.
2) Would I really post here without having a good look at the source first?

EDIT: I found it in sprk.c ! :
if (ct==PT_NSCN && rt==PT_PSCN)
conduct_sprk = 0;
