Syntax of OBJECT Parameter
technology programming languages

  1. //STEP1 EXEC PGM=IDCAMS //SYSPRINT DD SYSOUT=* //DD1 DD DSN=USERID.KSDS.BACKUP,DISP=SHR //SYSIN DD * IMPORT INFILE(DD1) OUTDATASET(USERID.TEST.VSAM) /*

  2. //STEP1 EXEC PGM=IDCAMS //SYSPRINT DD SYSOUT=* //DD1 DD DSN=USERID.KSDS.BACKUP,DISP=SHR //SYSIN DD * IMPORT INFILE(DD1) OUTFILE(USERID.TEST.VSAM) /*

  3. //STEP1 EXEC PGM=IDCAMS //SYSPRINT DD SYSOUT=* //DD1 DD DSN=USERID.KSDS.BACKUP,DISP=SHR //SYSIN DD * IMPORT INDATASET(DD1) OUTDATASET(USERID.TEST.VSAM) /*

  4. //STEP1 EXEC PGM=IDCAMS //SYSPRINT DD SYSOUT=* //DD1 DD DSN=USERID.KSDS.BACKUP,DISP=SHR //SYSIN DD * IMPORT INDATASET(DD1) OUTFILE(USERID.TEST.VSAM) /*

Show answer
Correct Option: A
Explanation:

To understand the syntax of the OBJECT parameter, we need to understand what is IDCAMS. IDCAMS stands for Access Method Services, and it is used to access VSAM data sets. The IMPORT statement is used to copy records from one VSAM data set to another.

The syntax of the OBJECT parameter is as follows:

IMPORT INFILE(input_ddname) OUTDATASET(output_dsname)

Here, the input_ddname is the DD statement that defines the input data set, and output_dsname is the data set name of the output VSAM data set.

Now, let's go through each option and determine which one has the correct syntax for the OBJECT parameter:

A. This option has the correct syntax for the OBJECT parameter. The input data set is defined by DD1, and the output data set is defined by USERID.TEST.VSAM.

B. This option has an incorrect syntax for the OBJECT parameter. The parameter should be OUTDATASET instead of OUTFILE.

C. This option has an incorrect syntax for the OBJECT parameter. The parameter should be INFILE instead of INDATASET, and OUTDATASET should be used instead of OUTFILE.

D. This option has an incorrect syntax for the OBJECT parameter. The parameter should be INFILE instead of INDATASET.

Therefore, the correct answer is: The Answer is A.
