     void *instanceface(modelface, symmetry)
     char modelface, symmetry;

PARAMETERS
     modelface		 Face of a connector in its figure.

     symmetry		 Geometrical  operation  applied to the instantiation of
			 the figure.

DESCRIPTION
     instanceface determines the orientation of a connector in	an  instance  of
     its model.

EXAMPLE
     #include "mph403.h"
     char channelFace(channelDir, i, c)
     char channelDir;
     phins_list *i;
     phcon_list *c;
     {
	if (channelDir == VER)
	   switch (instanceface(c->ORIENT, i->TRANSF)) {
	      case EAST :
		 return WEST;
	      case WEST :
		 return EAST;
	      default :
		 return instanceface(c->ORIENT, i->TRANSF);
	   }
	else
	   switch (instanceface(c->ORIENT, i->TRANSF)) {
	      case NORTH :
		 return SOUTH;
	      case SOUTH :
		 return NORTH;
