MSIR.0738 Assignment mismatch -- input is (clname), output is (clname)

An assignment from one object to another had a class mismatch or an assignment from one structure to another had a structure mismatch. Assignments between structure and object variables require that both the source and target have the same structure or class. If the source of the assignment is the result of a method, it is likely that there is a misunderstanding of the method result type, or, perhaps, the wrong method is being used. In such a case, check the documentation for the class to determine the method output type, and the appropriate method to use.
