Issue in passing comp variables to sub program in COBOL

Hi All,

I am trying to pass few comp variables to Sub program but its giving me a problem which is explained below:

Let say Main program 'A' calls to subprogram 'B'

Program A:

WORKING-STORAGE-SECTION.

01 WS-VARIABLES.
05 A PIC X(5)
05 B PIC 9(2)
05 C PC S9(4) COMP.

PROCEDURE DIVISION.
INITIALIZE WS-VARIABLES.

CALL B USING WS-VARIABLES

Program B:

LINKAGE-SECTION

01 WS-VARIABLES.
05 X PIC X(5)
05 Y PIC 9(2)
05 Z PC S9(4) COMP

PROCEDURE DIVISION USING WS-VARIABLES.

DISPLAY 'Value of Z: ' Z

Its displaying value of Z as 16448.

when I changed declaration of Z to 9(2) it showed value of Z as Spaces.This is fine as I am initializing WS-variables.

I am not able to find out reason behind the issue when using S9(4) comp.

I will be very thankful if anyone guide me on this.

Regards,
Chandan

how would decimal 16448 be stored in a COMP field? 4040

you are displaying a comp field. the display converts the comp to display.

10 seconds with a scientific calculator
(one of which is provided in your base PC software)
would have shown you the answer.

or

basic understanding of the display command.

understand the fundamentals and the complex things are easier to grasp.

You are not able to pass value or you are not able to display value??

chandan.inst,

I apologize for my attitude.
my intent was to explain the problem
and motivate you to think about things.

Though I was rude to you, you rose above the garbage and saw the point.
