8. SYSTEM-CALL RENAME METHOD m OF CLASS c NEW NAME FROM m2.

9. SYSTEM-CALL QUERY METHOD INCLUDE FROM incl CLASS INTO c
                                              METHOD INTO m.

SYSTEM-CALL CREATE METHOD m OF CLASS c INCLUDE INTO incl.


Addition:

... AS EXTENSION



Effect

Creates a method entry for method m in class c. The program name of the method include is returned in incl.

Return Value

SY-SUBRC = 0:
Entry for method m in class c created.
SY-SUBRC = 4:
Entry for method m in class c already exists.
SY-SUBRC = 8:
Overflow. Unable to create any more method entries for class c.

Addition

... AS EXTENSION

SY-SUBRC = 0:
Entry for method m in class c deleted.
SY-SUBRC = 4:
No entry for m in class c exists.

Variant 7

SYSTEM-CALL RENAME CLASS c NEW NAME FROM c2.

Basic entry for class c2 already exists.

Variant 8

SYSTEM-CALL RENAME METHOD m OF CLASS c NEW NAME FROM m2.


Effect

Renames the method entry m in class c using the new name m2.

Variant 9

SYSTEM-CALL QUERY METHOD INCLUDE FROM incl CLASS INTO c METHOD INTO m.


Addition:

... NO EXTENSIONS

Effect

The system checks whether or not a method entry exists for the method specified in the include name incl. If so, the class name in c and the method name in m.

Return Value

Class derived from include name incl does not exist.
SY-SUBRC = 8:
Method derived from include name incl does not exist.
