Which one of the following is incorrect

1. Divide A into B

2. Divide A by B

3. Divide A into B Giving C

4. Divide A by B Giving C

Correct Option: B

#### AI Explanation

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

Option A) Divide A into B - This option is correct because it implies that A is being divided into equal parts, with B representing the number of parts.

Option B) Divide A by B - This option is incorrect because it does not specify the result of the division. It is missing the information about what the division is giving or producing.

Option C) Divide A into B Giving C - This option is correct because it specifies that A is being divided into B equal parts and the result of the division is C.

Option D) Divide A by B Giving C - This option is correct because it specifies that A is being divided by B, and the result of the division is C.

The correct answer is B.

Determine the size of the data item SPPPP9999

1. 9

2. 5

3. 8

4. 4

Correct Option: D

#### AI Explanation

To determine the size of the data item SPPPP9999, we need to understand how the data item is structured.

The data item SPPPP9999 consists of a combination of letters and numbers. Let's break it down:

• The first character, "S", is a letter.
• The next four characters, "PPPP", are letters.
• The final four characters, "9999", are numbers.

In most programming languages, each character is usually stored using 1 byte of memory. Therefore, the size of the data item SPPPP9999 can be calculated as follows:

1 byte (for the first character "S") + 4 bytes (for the next four characters "PPPP") + 4 bytes (for the final four characters "9999")

= 1 + 4 + 4

= 9

So, the correct answer is A) 9.

77-level entries are permitted in _________________.

1. Any part of the file section

2. Any part of the working-storage section

3. Any part of the data division

Correct Option: C

#### AI Explanation

To answer this question, you need to understand the concept of level entries in COBOL programming.

In COBOL, level numbers are used to define the structure and hierarchy of data items. The level number indicates the level of detail or complexity of the data item.

In this question, the correct answer is option C) Any part of the data division.

The data division is where data items and record structures are defined in a COBOL program. Level entries can be defined at any part of the data division, such as the file section, working-storage section, or linkage section. So, options A) and B) are incorrect.

Therefore, the correct answer is C) Any part of the data division. Level entries can be defined at any level in the data division to define the structure of the data used in the program.

Which one of the following is not a valid statement?

1. Multiply corresponding record1 by record2

2. Add corresponding record1 to record2

3. Move corresponding record1 to record2

4. Subtract corresponding record1 from record2

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) Multiply corresponding record1 by record2 - This option is not a valid statement because multiplying two records is not a well-defined operation. Multiplication is typically performed on individual values rather than entire records.

Option B) Add corresponding record1 to record2 - This option is a valid statement because adding two records is a valid operation. It involves adding corresponding values from each record.

Option C) Move corresponding record1 to record2 - This option is a valid statement. It suggests moving the values from record1 to record2.

Option D) Subtract corresponding record1 from record2 - This option is a valid statement because subtracting one record from another involves subtracting corresponding values from each record.

The correct answer is A. This option is not a valid statement because multiplying two records is not a well-defined operation.

1. 01 to 49 (both inclusive) and 77

2. 01 to 49 (both inclusive)

3. All odd numbers from 01 to 49

4. All even numbers from 01 to 49

Correct Option: B
1. Financial sector and engineering

2. Graphic design and education

3. None of these

Correct Option:
1. Comp

2. Comp-1

3. Display

4. Comp-3

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

1. Level 88

2. Level 77

3. Level 66

4. Level 01

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.

1. Dynamic CALL

2. Static CALL

3. Both A and B

4. None of the above

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

1. Even, Even

2. Odd, Even

3. Odd, Odd

4. Even, Odd

Correct Option: B

Which one is incorrect in the following??

1. If A is greater than B go to Para-A

2. If C is not positive go to Para-C

3. If D is not alphanumeric go to Para-D

4. If E = 3 or 4 go to Para-valid

Correct Option: C
