MSIR.0759 Order comparison (GE, LE, LT, GT) not valid for (what)

An order comparison was made between two structure or two object variables. Order comparisons (GE, LE, LT, and GT) are not supported for structures or objects. If an order comparison is required for a User Language class, define a method that performs the appropriate processing for an order comparison. Note that an equality comparison for an object only indicates equality if two object variables refer to the same object, not if they refer to two different objects with identical contents.
