I have a JCL which executes a program and passes a 4 byte data as a PARM as coded below

//STEP01 EXEC PGM=PROGRAM,PARM='HELL'

And in linkage section of the COBOL program the receiving field is of
size X(02).What will be the results during the runtime?

And if receiving field is of size 9(02)..what will happen?

Why can not you code a simple program to Test ur questions and also let us know the results.

01 WS-LINKAGE.
05 WS-LENGTH PIC S9(04) COMP.
05 WS-ABCD PIC X(02).

If you declare like this then WS-ABCD will hold two characters and you are loosing the other two characters.

Program will run fine but you will not get correct results.

If no of characters passed in PARM is more than
linkage section alpha numeric field declaration
In below example
Code:

01 WS-LINKAGE.
05 WS-LENGTH PIC S9(04) COMP.
05 WS-ABCD PIC X(02).


if you pass 'ABCDE' from PARM
WS-LENGTH will be correct i.e. 5
but WS-ABCD will have value 'AB' only
