A data item Var1 described with PIC S9(4) requires 3 bytes of storage if its usage clause is

cobol

  1. Comp

  2. Comp-1

  3. Display

  4. Comp-3

Show answer
Correct Option: D
Explanation:

To solve this question, the user needs to have an understanding of the different USAGE clauses in COBOL and the storage requirements for each of them.

  • A. Comp: This usage clause is a binary format that occupies 2 bytes of storage. Therefore, if the data item Var1 is described with PIC S9(4) and its usage clause is Comp, it would require 2 bytes of storage, which is less than the given 3 bytes. Hence, Option A is incorrect.

  • B. Comp-1: This usage clause is a packed decimal format that occupies 4 bytes of storage. Therefore, if the data item Var1 is described with PIC S9(4) and its usage clause is Comp-1, it would require 4 bytes of storage, which is more than the given 3 bytes. Hence, Option B is incorrect.

  • C. Display: This usage clause is an alphanumeric format that occupies 1 byte for each character of the data item. Since the data item Var1 is described with PIC S9(4), it would require 4 characters to store its value. Therefore, if the usage clause is Display, it would require 4 bytes of storage, which is more than the given 3 bytes. Hence, Option C is incorrect.

  • D. Comp-3: This usage clause is a packed decimal format that occupies 3 bytes of storage. Therefore, if the data item Var1 is described with PIC S9(4) and its usage clause is Comp-3, it would require 3 bytes of storage, which matches the given requirement. Hence, Option D is correct.

Therefore, the answer is: D. Comp-3.

Which level used in RENAME clause

cobol

  1. Level 88

  2. Level 77

  3. Level 66

  4. Level 01

Show answer
Correct Option: C

AI Explanation

To answer this question, we need to understand the RENAME clause in programming languages like COBOL.

In COBOL, the RENAME clause is used to change the name of a data item or a group of data items. The new name assigned to the data item or group is called the renamed item.

The level indicator in COBOL is used to specify the level of a data item or a group. It determines the hierarchical structure of the data item. The level numbers used in COBOL are 01, 66, 77, and 88.

Option A) Level 88 - This option is incorrect because the level 88 is used for condition names, not for renaming data items.

Option B) Level 77 - This option is incorrect because the level 77 is used for elementary data items, not for renaming data items.

Option C) Level 66 - This option is correct because the level 66 is used for renaming a data item or a group of data items.

Option D) Level 01 - This option is incorrect because the level 01 is used for the highest level of a data item or a group, but not specifically for renaming.

Therefore, the correct answer is C) Level 66. This option is correct because the level 66 is used in the RENAME clause to rename a data item or a group of data items.

In COBOL CANCEL statement used in which type of CALL
cobol

  1. Dynamic CALL

  2. Static CALL

  3. Both A and B

  4. None of the above

Show answer
Correct Option: A
Explanation:

To solve this question, the user needs to have knowledge of the COBOL programming language and the different types of CALL statements used in it.

The CANCEL statement is used to cancel an active COBOL program, either from within the program or by another program. Specifically, it is used to cancel a dynamic CALL statement.

Therefore, the correct answer is:

The Answer is: A. Dynamic CALL
