JCL Mock Test
This section presents you various set of Mock Tests related to JCL Framework. You can download these sample mock tests at your local machine and solve offline at your convenience. Every mock test is supplied with a mock test key to let you verify the final score and grade yourself.
JCL Mock Test IV
Q 1 - PROC1 is a in-stream procedure in a JCL and with this name PROC1 one catalog procedure exists, then which procedure will be invoked - catalog or in-stream?
//TXXXXX JOB ,, NOTIFY = &SYSUID // JCLLIB ORDER = (XXXXX.PROCLIB) //STEP1 EXEC PROC1 //PROC1 PROC //STEP1 EXEC PGM = IEFBR14 //DD1 DD DSN = TXXXXX.TEST, SPACE = (TRK,(1,1)), // DCB=(RECFM = FB, BLKSIZE = 8000, LRECL = 80), // DISP=(NEW,DELETE) //PEND
Answer : B
Explanation
Catalog procedure will be invoked.
Q 2 - What will be the output of following JCL which is calling a catalog procedure?
//TXXXXXJ JOB ,, NOTIFY = &SYSUID, CLASS = A, MSGCLASS = X // JCLLIB ORDER=XXXXX.PROC.LIBRARY //DATA1 EXEC PROC = PROC1, TIME = 3
Answer : B
Explanation
We are overriding the TIME parameter inside PROC1.
Q 3 - What is the name of program which will be executed in the STEP1?
//XXXXX JOB ,, NOTIFY = SYSUID, CLASS = A, MSGCLASS = X // SET A = PROG1 //STEP1 EXEC PGM = &A //DD1 DD DSN = FILE1, DISP = SHR
Answer : B
Explanation
SET statement is used to assign the values to symbolic parameters. So value of A is PROG1. So PROG1 will be executed in STEP1.
Q 4 - In-stream procedure is coded as a separate member of a PDS. State whether true or false?
Answer : B
Explanation
In-stream procedure is coded inside the JCL itself. So this statement is incorrect.
Answer : B
Explanation
Yes, a catalog procedure can call a in-stream procedure.
Q 6 - What are the type of procedure in JCL?
Answer : D
Explanation
Catalog and in-stream procedures are used in JCL.
Q 7 - Which method you will use to skip a particular step in JCL?
Answer : B
Explanation
You can use COND with the step. If condition is true step will be bypassed.
Answer : B
Explanation
PROC is used for declaring a procedure.
Q 9 - In order to execute step2 a job after a return code of 8 in step1, what condition you will code in step2?
Answer : B
Explanation
COND=(12,LT,STEP1), it will read the condition as 12 less than 8, which is false, so this step will be executed.
Q 10 - Up to which level cataloged and in-stream procedure can invoke other procedure?
Answer : B
Explanation
Cataloged and In-stream procedure can invoke other procedure up to 15 levels only.
Q 11 - If we have created a (+1) generation dataset in the first step of a job then how we can reference it in later steps of the same job for input?
Answer : C
Explanation
As we have created it in the same JCL, then we use (+1) as its reference.
Q 12 - If we want to use a GDG which is already created by some job, then how to use the reference of the last generation in a JCL?
Answer : C
Explanation
To refer the last generation of a GDG, we use the reference as (+0).
Answer : C
Explanation
We use & for symbolic parameters.
Q 14 - Which parameters we use in a JOB statement?
Answer : D
Explanation
We use positional and keyword parameters in a job statement.
Q 15 - How to send the execution status of a job to a user?
Answer : C
Explanation
We use NOTIFY parameter to send the status of a job.
Q 16 - Which statement is used to end the in-stream procedure in a JCL?
Answer : C
Explanation
PEND statement is used to end the in-stream procedure.
Q 17 - What units are used for allocation of output dataset?
Answer : C
Explanation
In mainframes, we use cylinders, tracks and blocks for allocation of datasets.
Q 18 - Which parameter is use to declare the name of dataset in DD statement?
Answer : C
Explanation
DSN is used to declare the name of dataset in a DD statement.
Q 19 - How do we pass values to a program through JCL?
Answer : C
Explanation
We can pass data to a program either by in-stream data (DD *) or by using PARM parameter.
Q 20 - Which utility is use to compile a COBOL program?
Answer : C
Explanation
We use IGYCRCTL utility to compile a COBOL program.
Q 21 - Which utility is used to run a COBOL-DB2 program?
Answer : B
Explanation
IKJEFT01 utility is used to run a COBOL-DB2 program.
Q 22 - What is the output of following JCL?
//STEP1 EXEC PGM = IEBEDIT //SYSUT1 DD DSN = XXXXXX.XXXX.XXXX(XXXXXXXX), DISP = SHR //SYSUT2 DD SYSOUT = (*,INTRDR) //SYSPRINT DD SYSOUT = * //SYSIN DD * EDIT TYPE = INCLUDE, STEPNAME = (STEP3,STEP7) /*
A - It will execute only STEP1
B - It will exclude STEP3 & STEP4 from execution
Answer : C
Explanation
This utility is used to run only particular steps in a JCL.
Answer : C
Explanation
?* is used to mark the end of in-stream data.
Q 24 - What DISP parameter we mention for creation of temporary dataset so that we can use it in later steps?
Answer : C
Explanation
PASS is valid only for normal disposition. This is used when the dataset is to be passed and processed by the next job step in a JCL.
Q 25 - Calling a procedure from within a procedure is called a nested procedure. Procedures can be nested up to 15 levels. State whether true or false?
Answer : B
Explanation
This is self explanatory.
