why is this so hard?
Consider a program A (ANY program written in RPG, MI, COBOL, CL, ...)
that calls program B (written in COBOL). A does this:

begin
    number P
    call B (P)
    call B (P)
    call B (P)
    print P
end

B looks like this:
...
77  MY-COUNT  PIC 9999 VALUE ZERO.

LINKAGE SECTION.
01  THE-PARM PIC 9999.

PROCEDURE DIVISION USING THE-PARM.
BEGIN-ME.
     ADD 1 TO MY-COUNT
     MOVE MY-COUNT TO THE-PARM
     .
END-ME.
    EXIT PROGRAM
    .
STOP-ME.
    STOP RUN
    .

======

Program A will print the number 3.
QED.

It does that because:
1) the run unit is not terminated
2) EXIT PROGRAM is executed
