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.

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.

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.
