Please go through the code, is it pass by value?

Can any one explain me the diff between call by value and call by reference in Subroutines.

ex :

PERFORM ADD_Z1CLASS1 USING LW_MARA-MATNR

CHANGING IDOC_DATA[].

FORM ADD_Z1CLASS1 USING PV_MATNR TYPE MATNR

CHANGING PT_EDIDD TYPE EDIDD_TT.

Please let me know, if the above code is call by value or call by reference...?

Any suggestions will be appreciated!
