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.

Correct Option: C

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

using an ____number of digits for PACKED DECIMAL (COMP-3) is 5% to 20% Faster than using an_____ number of digits .

cobol

  1. Even, Even

  2. Odd, Even

  3. Odd, Odd

  4. Even, Odd

Show answer
Correct Option: B

AI Explanation

To answer this question, you need to understand the concept of PACKED DECIMAL (COMP-3) and how the number of digits affects its performance.

PACKED DECIMAL (COMP-3) is a data type used in computer programming to store decimal numbers. It is commonly used in languages like COBOL. In this format, each digit is encoded in a nibble (half a byte), and the sign is stored in the last nibble.

Now let's analyze each option to understand why the correct answer is option B:

Option A) Even, Even - This option suggests using an even number of digits for PACKED DECIMAL (COMP-3) in both cases. However, this is not the correct answer because the performance is not affected by using an even number of digits in both cases.

Option B) Odd, Even - This option suggests using an odd number of digits for PACKED DECIMAL (COMP-3) in the first case and an even number of digits in the second case. This is the correct answer because using an odd number of digits in the first case can result in faster performance compared to using an even number of digits.

Option C) Odd, Odd - This option suggests using an odd number of digits for PACKED DECIMAL (COMP-3) in both cases. However, this is not the correct answer because the performance is not affected by using an odd number of digits in both cases.

Option D) Even, Odd - This option suggests using an even number of digits for PACKED DECIMAL (COMP-3) in the first case and an odd number of digits in the second case. However, this is not the correct answer because the performance is not affected by using an odd number of digits in the second case.

Therefore, the correct answer is option B) Odd, Even. This option is correct because using an odd number of digits for PACKED DECIMAL (COMP-3) can result in faster performance compared to using an even number of digits.
