Correct Option: A

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

technology programming languages

  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

Show answer
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.

Therefore, the correct answer is:

The Answer is: A

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

technology programming languages

  1. True

  2. False

Show answer
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 Answer is: A

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

technology programming languages

  1. (a) 8MB

  2. (b) 31MB

  3. (c) 16MB

  4. (d) 20MB

Show answer
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 ----.

technology programming languages

  1. (a) 18 , zero

  2. (b) zero , 18

  3. (c) zero , 9

  4. (d) 9 , zero

Show answer
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.

RMODE stands for ?

technology programming languages

  1. (a) Remote mode

  2. (b) Regression mode

  3. (c) Recession mode

  4. (d) Residency mode

Show answer
Correct Option: D

AI Explanation

To answer this question, we need to understand what RMODE stands for.

RMODE stands for Residency mode.

Option A) Remote mode - This option is incorrect because RMODE does not stand for Remote mode. Option B) Regression mode - This option is incorrect because RMODE does not stand for Regression mode. Option C) Recession mode - This option is incorrect because RMODE does not stand for Recession mode. Option D) Residency mode - This option is correct because RMODE stands for Residency mode.

Therefore, the correct answer is option D) Residency mode.
