The problem was what the final values for B[1] and B[2] are,
using different forms of parameter passing in the following
ALGOL-like program:
-----
	BEGIN INTEGER I; INTEGER ARRAY B[1,2];
		PROCEDURE Q(X); INTEGER X;
		BEGIN I := 1; X := X + 2; B[I] := 10;
		      I := 2; X := X + 2;
		END;
	  B[1] := 1; B[2] := 1; I := 1; Q(B[I]);
	END;
-----
 call by..   B[1] B[2]
reference      12   1
value          10   1
value result    5   1
result       undef  1
name           10   3
