Answer / vinod babu bachina

when PROGA made a call to PROGB, if it is first time then
the execution in PROGB start from workign storage
section.suppose progA calls again PROGB then the execution
will start from procedure division only .So when we made a
second call to anu subprogram we have to intialize the
working storage section variables.otherwise second call
retains the values of first call.

Answer / rajagopalan

The variables in the working-storage section of prog-b will
be initialized only if prog-a has given a CANCEL statement
after CALL statement. Othrwise the WS variables of prog-B
will retain the latest contents of the previous call.

Answer / s.rajagopalan

none of the above answer is correct.
In static call the working storage varibales is not
initialised when the sub program is called. It retains the
latest values of ws variables in the subrpogram.

In case of dynamic call if you use "cancel" stament then
the ws variables of the sub program are initialised.
if you dont use cancel statement and call the subprogram
then the latest values are retained for the WS vriables.

Answer / nagesh

Well, it depends on the type of call u r making, if it's
dynamic call working storage variable will be initialized
every time automatically.
But if it's static call u can use either 'cancel' or
'is initial' .

Answer / ab

I think Nagesh's answer is correct.
