IBM COBOL400 Interview Question:

What are Fillers?
What is the actual use of Fillers? With mall/simple Example?

Submitted by: Administrator

When a programmer is not intended to use any fields in a record structure, it can be defined as Filler.
This can't be initialized or used in any operation of the procedure division.


Eg: if a record contains the following fields
05 EMP-REC.
10 EMP-KEY PIC XXX.
10 EMP-NAME PIC X(32).
10 EMP-SEX PIC X.
10 EMP-DEPT PIC X(10)
10 EMP-DESIG PIC X(5).
10 EMP-SAL PIC 9(7).


If the programmer is not intended to use , name ,dept and sal in the program the u can define the structure as follows
05 EMP-REC.
10 EMP-KEY PIC XXX.
10 FILLER PIC X(32).
10 EMP-SEX PIC X.
10 FILLER PIC X(10)
10 EMP-DESIG PIC X(5).
10 FILLER PIC 9(7).
