Clear or overwrite EXPORTING reference parameters

Reference parameters refer to existing memory areas that may be filled beforehand. Clear or overwrite them to provide reliable data:

METHODS square
  EXPORTING
    result TYPE i.

" clear
METHOD square.
  CLEAR result.
  " ...
ENDMETHOD.

" overwrite
METHOD square.
  result = cl_abap_math=>square( 2 ).
ENDMETHOD.

Code inspector and Checkman point out EXPORTING variables that are never written. Use these static checks to avoid this otherwise rather obscure error source.

Take care if input and output could be the same
