AMS commands can be run from TSO prompt

  1. True

  2. False


Correct Option: A

AI Explanation

To answer this question, you need to understand the concepts of AMS commands and TSO prompt.

Option A) True - This option is correct. AMS (Access Method Services) commands can indeed be run from the TSO (Time Sharing Option) prompt. TSO is an interactive command processor that allows users to enter commands to perform various tasks on an IBM mainframe system. AMS commands are used for managing and manipulating datasets and resources on the mainframe system, such as creating, deleting, renaming, or copying datasets.

Option B) False - This option is incorrect. AMS commands can be run from the TSO prompt, so the correct answer is A) True.

The correct answer is A) True. This option is correct because AMS commands can be executed from the TSO prompt.

FREESPACE can be specified in ESDS

  1. True

  2. False


Correct Option: B

file status on 02 on a VSAM dataset indicates duplitcate alternate key.

  1. True

  2. False


Correct Option: A

Correct Option: C

Can we MOVE Alphanumeric to numeric edited?

  1. Yes. We can move

  2. Only if the sending field is an unsigned integer.

  3. No. We cannot move

  4. Only if the sending field is signed integer.


Correct Option: B

In PIC zzz9, What does z means?

  1. zero comp digit

  2. zero suppressed digit

  3. zero edited digit

  4. zero packed digit


Correct Option: B

AI Explanation

To answer this question, you need to understand the format specifier "zzz9" in PIC (Picture) clause used in COBOL programming.

In PIC zzz9, the "z" represents a zero suppressed digit.

Option A) Zero comp digit - This option is incorrect because "z" does not stand for zero comp digit. Zero comp digit is represented by "9" in COBOL. Option B) Zero suppressed digit - This option is correct because "z" in PIC zzz9 represents a zero suppressed digit. Option C) Zero edited digit - This option is incorrect because "z" does not stand for zero edited digit. Option D) Zero packed digit - This option is incorrect because "z" does not stand for zero packed digit.

The correct answer is B) Zero suppressed digit. This option is correct because "z" in PIC zzz9 represents a zero suppressed digit.

  1. Area A

  2. Area B

  3. All of the above

  4. None of the above


Correct Option: A

  1. 523

  2. 231

  3. +523

  4. -523


Correct Option: B

Which is the correct ASCII collating sequence?

  1. spaces,a-z,A-Z,0-9,special characters

  2. a-z,A-Z,0-9,spaces,special characters

  3. 0-9,special characters,spaces,a-z,A-Z

  4. spaces,special characters,0-9,A-Z,a-z


Correct Option: D

The COBOL perform loop is the equivalent of which of the following structures found in other languages such as Java or C++

  1. For loop

  2. Do-While loop

  3. Method

  4. All of the above

  5. None of the above


Correct Option: B

If someone wanted a COBOL perform "loop" to execute once before the condition is checked, which of the following would they do?

  1. use a standard perform statement

  2. use an in line perform

  3. skillful use of the COBOL reserved word "AFTER"

  4. This is not possible in COBOL


Correct Option: C

Not Negative means

  1. Equal to 0

  2. Greater than or equal to 1

  3. Less than or equal to 0

  4. Greater than or equal to 0


Correct Option: D

  1. VOTC

  2. COTV

  3. VTOC

  4. COVT


Correct Option: C

What is the use of IEHPROGM utility?

  1. To maintain and manage catalogs

  2. To compare two datasets at record level

  3. It is a null program

  4. To copy a VSAM dataset to a flat file


Correct Option: A

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) To maintain and manage catalogs - This option is correct. The IEHPROGM utility is used to maintain and manage catalogs in IBM mainframe systems. Catalogs contain information about datasets, such as their names, types, and locations. The utility allows you to create, update, and delete catalog entries.

Option B) To compare two datasets at record level - This option is incorrect. The IEHPROGM utility is not used to compare datasets at the record level. There are other utilities, such as IEBGENER or IEBGENER, that can be used for dataset comparisons.

Option C) It is a null program - This option is incorrect. The IEHPROGM utility is not a null program. It is a utility program with a specific purpose.

Option D) To copy a VSAM dataset to a flat file - This option is incorrect. The IEHPROGM utility is not used to copy a VSAM dataset to a flat file. There are other utilities, such as IDCAMS or IEBGENER, that can be used for dataset copying.

The correct answer is A) To maintain and manage catalogs. This option is correct because the IEHPROGM utility is specifically designed for maintaining and managing catalogs in IBM mainframe systems.
