The ExtCallNode structure points to an ExternalFunc structure and holds a list of instances which are tied to the arguments in the calling ASCEND statement. -- JP
It seems that we shouldn't be accessing this structure at solve-time: the ExtRelCache object contains a lot of pre-processed stuff that makes evaluating black box functions easier (probably glass box too?) -- JP
Complete documentation of compiler/extcall.h.
In the context of an ExtCallNode (at least in the case of black box relations) the 'subject' is the output variable for the particular relation within the black box. There is 'relation' created for each output variable, as required for the [eye(NxN), ones(NxM)] submatrix in the jacobian. -- JP
