at_posn function
at_posn(C)
at_posn(C,Row,Col)
Must form the whole equation of a component. Sets the component's value to the value of a component in an instance of a 2-D submodel representing a grid. C is the caption of the component in the grid submodel, and Row and Col if present are the outer and inner indices of the source instance (i.e., grid square) from which to get the value. If Row and Col are not present, the grid is mapped onto the diagram of the submodel containing the target component and the source instance selected by the component's position in the submodel diagram.
