Is INITIALIZE costly as regards performance

I have the following scenario.

I have a progam (Say A) .Input to A is a file which it reads ,builds a pass area and calls prog B for each record in the input file.Prog B further doea the processing of the data it receives via linkage from A.

When I Expedite A and go to B I see values of previous records(say i am on 2 nd record then i see values of 1st record on reaching Procedure Division of B).

My query is that the data receiving layouts in prog B are in working storage so for each call the layouts should get initialized automatically.
Still the values of previous record persist.

Can someone help me?.According to what i understand is that coz the program resides in the memory so the values of previous records are there.

I tried using INITIALIZE but was told that it is costly as regards performance.

Is there any other alternative.

Thanks in advance.

Regards,
Tushar

You mean that program B is getting the wrong values?
or simply that wandering thru storage You see old things left around ??

case 1... correct Your program(s)
case 2... nothing to worry about
( if You had the authority wander thru the memory of Your system You would see lots of older dat laying around )

Another way will be to use INITIAL attribute for your subprogram.

I would not suggest any solution until the O/P has answered my prevoius questions

if the programs have been properly written
the subprograms has NO need to initialize the area where parameters are being passed...
it' s a caller responsibility to provide proper data to the called program
