compatible
With the exception of reference variables, two non- generic data types are compatible if all their technical attributes are the same. Any data type is compatible with a generic data type if the generic data type includes its technical attributes. Data objects are compatible if their data types are compatible. Compatibility is the basis for checking the typing. In the case of an assignment or comparison of compatible data objects, no conversion takes place.
