Data Objects and Data References in Release 4.6A

In ABAP_99A , references to data objects have been introduced in the following variants:

1 Reference variables for data objects 2 Creating data objects and getting references 3 Assignment of referenced fields

ABAP_MODIFICATION_1 Reference Variables for Data Objects

Previously, reference variables were only available in ABAP Objects. In Release 4.6A, DATA f TYPE REF TO DATA can be used to declare f as a reference variable that points to a different data object.

ABAP_MODIFICATION_2 Creating Data Objects and Getting References

CREATE DATA dref ... can be used to create a new data object (field) at runtime, where dref can be any reference variable with type REF TO DATA . Furthermore, GET REFERENCE can be used to get a reference to a data object (field).

ABAP_MODIFICATION_3 Assignment of Referenced Fields

The statement ASSIGN dref->* TO <(><<)>fs> makes the field symbol <(><<)>fs> point to the same content as the data reference dref at runtime. If the field symbol is typed, the type is checked when the assignment is made.
