Is it possible ?
DATA : f1 TYPE string VALUE '1',
       f2 TYPE string VALUE '2',
       f3 TYPE string VALUE '3',
       f4 TYPE string VALUE '4'.
DATA : f1o TYPE string ,
       f2o TYPE string ,
       f3o TYPE string,
       f4o TYPE string.
PERFORM call_fm USING f1 CHANGING f1o.
PERFORM call_fm USING f2 CHANGING f2o.
PERFORM call_fm USING f3 CHANGING f3o.
PERFORM call_fm USING f4 CHANGING f4o.
WRITE f1o.
WRITE f2o.
WRITE f3o.
WRITE f4o.
