Hi senthil,
Thanks for the reply.
can we use both call by value and call by reference in a single call.
if we do not mention any call by reference or value does it take default call by reference or call by value. |

Dear Friends,
You can use CALL BY VALUE and CALL BY CONTENT in a single Call statement.
Default is CALL BY REFERENCE, So if you miss anything, it's treated as CALL BY REFERENCE.
Ex: CALL A USING B, C BY CONTENT, D BY REFERENCE. |

answer
call by reference and call by value are types of static call
if you look in calling programme then
1] for call by reference : in procedure division there is mntion verb USING REFERENCE OR not mention because it is in default
2] for call by content (value ): in procedure division there compulsory mention the verb USING CONTENT
I GIVEN YOU EXAMPLES
EXAMPLE1.CALL BY CONTENT
ID DIVISION
PROGRAM-ID. XXX.
WORKING-STORAGE SECTION.
LINKAGE SECION.
77 A PIC 9(2).
77 B PIC 9(4).
77 C PIC 9(6).
PROCEDURE DIVISION USING CONTENT OF A, B, C.
COMPUTE C = A + B
DISPLAY C
EXAMPLE2.CALL BY REFERENCE
ID DIVISION
PROGRAM-ID. XXX.
WORKING-STORAGE SECTION.
LINKAGE SECION.
77 A PIC 9(2).
77 B PIC 9(4).
77 C PIC 9(6).
PROCEDURE DIVISION USING REFERENCE OF A, B, C.
COMPUTE C = A + B
DISPLAY C |
