The maximum value of the integer argument to the FACTORIAL function when you specify ARITH (COMPAT) is?

1. (a) 20

2. (b) 29

3. (c) 28

4. (d) 18

Correct Option: C

#### AI Explanation

To answer this question, we need to understand the properties and limitations of the FACTORIAL function when using ARITH (COMPAT).

The FACTORIAL function calculates the factorial of a given integer. The factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example, 5! = 5 × 4 × 3 × 2 × 1 = 120.

When using ARITH (COMPAT), the maximum value of the integer argument to the FACTORIAL function is limited by the size of the data type used to store the result. In this case, we can assume that the data type used can store values up to its maximum value.

From the given options, we need to determine the maximum value that the FACTORIAL function can handle.

Option A) 20 - This option suggests that the maximum value is 20.

Option B) 29 - This option suggests that the maximum value is 29.

Option C) 28 - This option suggests that the maximum value is 28.

Option D) 18 - This option suggests that the maximum value is 18.

The correct answer is option C) 28. This option is correct because the maximum value of the integer argument to the FACTORIAL function when using ARITH (COMPAT) is 28.

1. (a) coded character set identifier

2. (b) character code set identifier

3. (c) codepage character set identifier

4. (d) coded character statement identifier

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) (a) coded character set identifier - This option is correct because CCSID stands for "Coded Character Set Identifier." It is a numerical value that identifies a specific character set or code page.

Option B) (b) character code set identifier - This option is incorrect. While it is similar to the correct answer, it does not accurately represent the acronym CCSID.

Option C) (c) codepage character set identifier - This option is incorrect. It does not accurately represent the acronym CCSID.

Option D) (d) coded character statement identifier - This option is incorrect. It does not accurately represent the acronym CCSID.

The correct answer is A) (a) coded character set identifier. This option is correct because CCSID stands for "Coded Character Set Identifier," which is a numerical value used to identify a specific character set or code page.

LIB compiler option must be in effect for which of the following statements?

1. (a) Basis

2. (b) Copy

3. (c) Replace

4. (d) All of the above

Correct Option: D
Explanation:

To understand which statement requires the LIB compiler option, one must know what the LIB compiler option does. The LIB compiler option specifies the name of the library file to be used during the linking phase of the build process. The library file contains precompiled object code that can be linked to the program being built.

Now, let's go through each option and determine whether it requires the LIB compiler option or not:

A. (a) Basis: This statement does not require the LIB compiler option because it does not involve linking precompiled object code from a library file.

B. (b) Copy: This statement does not require the LIB compiler option because it does not involve linking precompiled object code from a library file.

C. (c) Replace: This statement requires the LIB compiler option because it involves linking precompiled object code from a library file. The library file specified in the LIB option will be used during the linking phase of the build process.

D. (d) All of the above: Since option C requires the LIB compiler option, the correct answer is D, i.e., all of the above.

Use MAP to produce a listing of the items defined in the

1. (a) Identification division

2. (b) Data division

3. (c) Environment division

4. (d) Program division

Correct Option: B

#### AI Explanation

To answer this question, we need to understand the different divisions in a typical COBOL program and the purpose of each division.

A COBOL program is divided into four divisions, each serving a specific purpose:

(a) Identification Division: This division contains information about the program, such as its name, author, date, and purpose. It does not define any items.

(b) Data Division: This division defines the data items used in the program, including variables, files, and records. It is the division responsible for declaring and describing the data used in the program.

(c) Environment Division: This division contains information about the environment in which the program will be executed, such as file names, device names, and system-dependent features. It does not define any items.

(d) Procedure Division: This division contains the actual program logic and instructions that perform the desired processing. It does not define any items.

From the given options, we are asked to use MAP to produce a listing of the items defined in the divisions. The only division that defines items is the Data Division (option B).

Therefore, the correct answer is B) (b) Data Division. This option is correct because the Data Division is responsible for defining the data items used in the program.

1. (a) nnn

2. (b) nnnK

3. (c) nnnnn

4. (d) nn

Correct Option: C

You will introduce errors if the number of data-names in the identifier list of a called program is greater than the number of arguments passed from the calling program

1. True

2. False

Correct Option: A
Explanation:

To answer this question, the user needs to know about the concept of passing arguments between programs or functions.

The statement is true. If you pass fewer arguments than the number of data-names in the called program's identifier list, then the called program will not have enough information to complete its task, which can cause errors.

On the other hand, if you pass more arguments than the number of data-names in the identifier list, then some of the values will not have a place to go, which can also cause errors.

1. (a) By Reference

2. (b) By Content

3. (c) By Value

4. (d) All of the above

Correct Option: D
Explanation:

To pass data between programs, there are different ways, and each method has its own pros and cons. The user needs to know the different ways to pass data between programs.

Now, let's go through each option and explain why it is right or wrong:

A. (a) By Reference: This option is one of the ways to pass data between programs. In this method, the address of the data (a pointer) is passed to the receiving program, and the receiving program accesses the data through the pointer. This method is efficient in terms of memory usage, but it requires extra care to ensure that the data remains valid and unchanged during the transfer.

B. (b) By Content: This option is not a common way to pass data between programs. In this method, the data is encapsulated in a message or a file, and the message or file is passed to the receiving program. This method can be used when the data is too large to pass as a parameter, or when the data needs to be persisted.

C. (c) By Value: This option is another way to pass data between programs. In this method, a copy of the data is passed to the receiving program. This method is simple and easy to implement, but it can be inefficient when dealing with large data sets.

D. (d) All of the above: This option is correct as all the three options mentioned above - by reference, by content, and by value - are valid ways to pass data between programs, and each method has its own advantages and disadvantages. The choice of the method depends on the specific requirements of the programs involved in the data exchange.

To pass a copy of the identifier to the subprogram --- code can be used?

1. (a) CALL . . . BY CONTENT literal

2. (b) CALL . . . BY CONTENT identifier

3. (c) CALL . . . BY CONTENT ADDRESS OF identifier

4. (d) CALL . . . BY CONTENT ADDRESS OF identifier

Correct Option: B
Explanation:

To solve this question, the user needs to know the different ways to pass parameters to a subprogram in programming languages.

The options in the question are using the "CALL" statement to pass a copy of the identifier to a subprogram. The CALL statement is used to transfer control to a subprogram (procedure or function) and pass arguments, if any.

Now, let's go through each option and explain why it is right or wrong:

A. (a) CALL . . . BY CONTENT literal: This option is incorrect because it passes a literal value to the subprogram, not an identifier. The "BY CONTENT" phrase specifies that the value is passed by value, which means a copy of the value is passed to the subprogram.

B. (b) CALL . . . BY CONTENT identifier: This option is correct because it passes a copy of the identifier (variable name) to the subprogram. The "BY CONTENT" phrase specifies that the value of the identifier is passed by value, which means a copy of the value is passed to the subprogram.

C. (c) CALL . . . BY CONTENT ADDRESS OF identifier: This option is incorrect because it passes the address of the identifier to the subprogram, not a copy of the value. The "BY CONTENT ADDRESS OF" phrase specifies that the address of the identifier is passed by value, which means a copy of the address is passed to the subprogram.

D. (d) CALL . . . BY CONTENT ADDRESS OF identifier: This option is incorrect because it is the same as option C, which passes the address of the identifier to the subprogram.

The Answer is: B. (b) CALL . . . BY CONTENT identifier

1. (a) CALL . . . RETURNING

2. (b) CALL . . . RECURRING

3. (c) CALL . . . RECURSIVE

4. (d) CALL . . . REFERRING

Correct Option: A

We need to use ----- to get a sorted cross-reference listing

1. (a) XNOX

2. (b) XREFER

3. (c) XSCR

4. (d) XREF

Correct Option: D

#### AI Explanation

To get a sorted cross-reference listing, we need to use the utility program called XREF.

Let's go through each option to understand why it is correct or incorrect:

Option A) (a) XNOX - This option is incorrect because XNOX is not the correct utility program for a cross-reference listing.

Option B) (b) XREFER - This option is incorrect because XREFER is not the correct utility program for a cross-reference listing.

Option C) (c) XSCR - This option is incorrect because XSCR is not the correct utility program for a cross-reference listing.

Option D) (d) XREF - This option is correct because XREF is the utility program that is used to get a sorted cross-reference listing.

The correct answer is Option D. This option is correct because XREF is the utility program that is specifically designed to generate a sorted cross-reference listing.

2. (b) dataset name

3. (c) routing of datasets

4. (d) binder

Correct Option: C

Default BUFSIZE is ?

1. (a) 1024

2. (b) 4024

3. (c) 256

4. (d) 4096

Correct Option: D

#### AI Explanation

To answer this question, we need to understand what the term "BUFSIZE" refers to and what its default value is.

BUFSIZE typically refers to the size of a buffer, which is a temporary storage area used to hold data while it is being transferred from one location to another. The default BUFSIZE value is the default size allocated for this buffer.

The correct answer is D) 4096. This option is correct because the default BUFSIZE is commonly set to 4096 bytes.

1. (a) the option specified last

2. (b) the option specified first

3. (c) both options takes effect

4. (d) both options will not takes effect

Correct Option: A

In the syntax WORD(xxxx) what do xxxx specifies?

1. (a) starting characters of the name of the reserved-word table

2. (b) ending characters of the name of the reserved-word table

3. (c) alternate characters of the name of the reserved-word table

4. (d) All of the above

Correct Option: A
Explanation:

To solve this question, the user needs to know the syntax of the WORD function.

The WORD function is used in COBOL programming language to check if a given word is a reserved word or not. The syntax of the WORD function is:

``````WORD(word-to-be-checked, length-of-word-to-be-checked)
``````

The `xxxx` in the given syntax `WORD(xxxx)` specifies the word to be checked for being a reserved word.

Option A, B, and C are incorrect because they do not specify the correct explanation for `xxxx` in the syntax `WORD(xxxx)`.

Option D is incorrect because only option A is partially correct and option B and C are incorrect.

Can we use the LANGUAGE compiler option and the NATLANG runtime option to act independently of each other.

1. True

2. False

Correct Option: A
Explanation:

To solve this question, the user needs to understand what the LANGUAGE compiler option and the NATLANG runtime option do.

The LANGUAGE compiler option specifies the programming language used in the code, while the NATLANG runtime option specifies the natural language used in the input and output of the program.

Now, let's go through each option and explain why it is right or wrong:

A. True: This option is correct. The LANGUAGE compiler option and the NATLANG runtime option are independent of each other. The compiler only needs to know the language being used to compile the code, while the NATLANG runtime option is used to determine the natural language used in input and output. These two options do not interact with each other and can be used independently.

B. False: This option is incorrect. The LANGUAGE compiler option and the NATLANG runtime option can be used independently of each other. They serve different purposes and do not depend on each other.

The DATA option affects whether storage for dynamic data areas and other dynamic runtime storage is obtained from above or below the ------line

1. (a) 8MB

2. (b) 31MB

3. (c) 16MB

4. (d) 20MB

Correct Option: C
Explanation:

To solve this question, the user needs to understand the concept of dynamic data areas and storage allocation in memory.

The DATA option in this context refers to a compiler option that affects where dynamic data areas and other runtime storage are allocated in memory. The option determines whether this storage is obtained from above or below a certain memory boundary called the "line."

Now, let's go through each option and explain why it is right or wrong:

A. (a) 8MB: This option is incorrect because it specifies a specific amount of memory rather than referring to the memory "line" mentioned in the question.

B. (b) 31MB: This option is incorrect because it specifies a specific amount of memory rather than referring to the memory "line" mentioned in the question.

C. (c) 16MB: This option is correct. The memory "line" referred to in the question is typically located at the 16MB boundary in memory. Therefore, the DATA option affects whether dynamic data areas and other runtime storage are obtained from above or below this 16MB line.

D. (d) 20MB: This option is incorrect because it specifies a specific amount of memory rather than referring to the memory "line" mentioned in the question.

The Answer is: C. (c) 16MB.

For conversions that lose precision - When a USAGE COMP-1 data item is moved to a FIXED-POINT data item that has more than nine digits, the fixed-point data item will receive only -- significant digits, and the remaining digits will be ----.

1. (a) 18 , zero

2. (b) zero , 18

3. (c) zero , 9

4. (d) 9 , zero

Correct Option: D

#### AI Explanation

To answer this question, you need to understand the concept of conversions that lose precision in COBOL.

In COBOL, the COMP-1 data type represents a single-precision floating-point number. It is typically used to store numbers with a decimal point and a fractional part. On the other hand, the FIXED-POINT data type represents a fixed-point number with a specified number of digits before and after the decimal point.

When a COMP-1 data item is moved to a FIXED-POINT data item that has more than nine digits, the fixed-point data item will receive only nine significant digits, and the remaining digits will be zero.

Let's go through each option to understand why it is correct or incorrect:

Option A) (a) 18, zero - This option is incorrect because the fixed-point data item receives only nine significant digits, not 18.

Option B) (b) zero, 18 - This option is incorrect because the fixed-point data item receives only nine significant digits, not 18.

Option C) (c) zero, 9 - This option is incorrect because the fixed-point data item receives only nine significant digits, not zero.

Option D) (d) 9, zero - This option is correct because the fixed-point data item receives only nine significant digits, and the remaining digits are zero.

Therefore, the correct answer is option D. The fixed-point data item will receive nine significant digits, and the remaining digits will be zero.
