I have a calling program as below :

01 WS-AREA-PASSED X(500).
01 WS-AREA-NOT-PASSED X(100).
CALL WS-PGM USING WS-AREA-PASSED.

Called program WS-PGM looks like :

LINKAGE SECTION.
01 WS-AREA-PASSED X(500).
PROCEDURE DIVISION USING WS-AREA-PASSED.
-------

When the data sent to WS-AREA-PASSED is greater than 500 chars,
Some of the data is carried over to WS-AREA-NOT-PASSED.

Is this overflow possible ? How can a called program update any WS area in the calling program without being passed to it ?

Please clarify.

Called program has the address of WS-AREA-PASSED of calling program. It is replacing data there depending the length of WS-AREA-PASSED of called program.
