Hi Friends this Vijai, I recently attend a Mainframe interview in Chennai. I share some Mainframe interview questions With you, What I remember …….

COBOL Questions:

1. Program name: P1.
Load library: TRGF99.COBOL.LOADLIB
Input File: TRGF99.FILE1
Output File: TRGF99.OUTFILE

//JOB1 JOB 124
//STEP01 EXEC PGM=P1
//STEPLIB DD DSN=TRGF99.COBOL.LOADLIB1,DISP=SHR
//INFILE DD DSN=TRGF99.FILE1,DISP=SHR
//OUTFILE DD DSN=TRGF99.OUTFILE,DISP=MOD

In the above scenario, if we execute the above program which one of the following errors we get?

a) S806 b)SE37 c)S0C4 d)S0C7
-------------------------------------------------------------------------------------------

2. If ‘MAINPGM’ is a COBOL program that calls another program ‘LINKPGM’ and passes a value say, ‘10’, that value will be accepted by another variable in link program. Where that variable is declared?

a) Working Storage Section of MAINPGM
b) Linkage Section of MAINPGM
c) Linkage Section of LINKPGM
d) Working Storage Section of LINKPGM
e) Both b & d
---------------------------------------------------------------------------------------

3. A file attribute mismatch was encountered. Which of the following status code is related to the above message?
a)35 b)39 c)46 d)90

c) 88 level variables are declared in Area-A.
d) 01 level variable is declared in Area-A.
-------------------------------------------------------------------------------
6. Every file entry in the File Control should have a description in the File Section.
a) True b) False
-----------------------------------------------------------------------------------
7. IF A>B
IF A>C
DISPLAY ‘A’
NEXT SENTENCE
END-IF
DISPLAY ‘C’
END-IF.
DISPLAY ‘B’.

If A=10, B=5, C=7. What is the output?

DISPLAY ‘IN MAIN-PARA’.
PERFORM PARA1 THRU PARA2.
STOP RUN.

PARA1.
DISPLAY ‘IN PARA1’.

PARA3.
DISPLAY ‘IN PARA3’.

PARA2.
DISPLAY ‘IN PARA2’.

Assume that the above code is in the PROCEDURE DIVISION of a COBOL program. If the above program is executed, what is the output?

a) IN MAIN-PARA b) IN MAIN-PARA c) IN MAIN-PARA
