To concatenate the dataset in JCL, code the DD statements continuously & give DDNAME only for first DD like shown below:
//NAME1 DD DSN=file.name1,DISP=SHR
// DD DSN=file.name2,DISP=SHR
// DD DSN=file.name3,DISP=SHR

Answer : B

Explanation

This is self explanatory.

Q 15 - A CHKPT is the parameter coded for multi-volume QSAM datasets in a DD statement. When a CHKPT is coded as CHKPT=EOV, a checkpoint is written to the dataset specified in the SYSCKEOV statement at the end of each volume of the input/output multi-volume dataset. State whether true or false?

Answer : B

Explanation

This is self explanatory.

Q 16 - Generation Data Groups (GDGs) are group of datasets related to each other by a common name. The common name is referred as GDG base and each dataset associated with the base is called a GDG version. State whether true or false?

Answer : B

Explanation

This is self explanatory.

Q 17 - SCRATCH option in GDG's physically deletes the generation when it is uncataloged. State whether true or false?

Answer : B

Explanation

This is self explanatory.

Q 18 - FORCE option in GDG's deletes the GDG versions and the GDG base. If any of the GDG versions are set with an expiration date which is yet to expire, then those are not deleted and hence the GDG base is retained. State whether true or false?

Answer : B

Explanation

This is self explanatory.

Q 19 - LIMIT option in GDG's specifies the maximum number of versions that the GDG base can hold. State whether true or false?

Answer : B

//STEP1 EXEC PGM = SORT
//SYSOUT DD SYSOUT = *
//SORTIN DD DSN = input.file.name
//SORTOUT DD DSN = output.file.name
//SYSIN DD *
    SORT FIELDS = COPY
    SUM FIELDS = NONE
/*

A - It will copy the data from input file to output file and will eliminate the duplicates

B - It will copy the data from input file to output file and will not eliminate the duplicates

C - It will copy the data from input file to output file

A - It will copy only those rows which starts from TUTORI from input file to output file.

Answer : A

Explanation

SUM FIELDS=NONE is used to eliminate the duplicate rows.

Q 23 - What is the output of following JCL?

//STEP1 EXEC PGM = SORT
//SYSOUT DD SYSOUT = *
//SORTIN DD DSN = input.file.name
//SORTOUT DD DSN = output.file.name
//SYSIN DD *
    SORT FIELDS = COPY
    INCLUDE=(1,6,CH,EQ,C'TUTORI')
/*

B - It will copy the data from input file to output file and will not eliminate the duplicates

C - It will copy the data from input file to output file

Answer : A

Explanation

It is used to include rows based on the condition that the first 6 characters should start from TUTORI and will ignore the rest.

D - All of these

Answer : D

Explanation

A procedure must not contain following statements : JOB statement, JOBLIB DD statement, DD * , DD DATA - In-stream data, delimiter statement, Null statement, JES statements, PEND statement (for cataloged procedures)

Q 25 - 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) 
//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
