What is the edited value of the picture clause PIC field 9999+ Numeric value moved to the field -382 and the Edited value is
- A.
0382-
- B.
3820-
- C.
-0038
- D.
-0003
Correct Answer
A. 0382-Explanation
The edited value of the picture clause PIC field 9999+ after moving the numeric value -382 to the field would be 0382-. This is because the picture clause specifies that the field should have 4 digits, and the plus sign indicates that it can also have a sign. The numeric value -382 is moved to the field and the resulting edited value is 0382- where the minus sign indicates the negative sign.Rate this question:

Initially A=30, B=60IF A = 40 DISPLAY ‘ABC’ ELSE NEXT SENTENCE END-IF MOVE 90 TO B. DISPLAY B. What is the output of the program?
- A.
30
- B.
60
- C.
90
- D.
Can’t perform the operation
Correct Answer
C. 90Explanation
The provided COBOL program initializes two variables, A and B, with values 30 and 60, respectively. It then checks if A is equal to 40. Since A is not equal to 40, it proceeds to assign the value 90 to B and displays the value of B, which is now 90. Therefore, the output of the program is "90."Rate this question:

In WRITE statement, it is required to mention the record name and not the file name.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In the WRITE statement, the record name should be mentioned instead of the file name. This means that when writing data to a file, the specific record within the file should be specified rather than just the file itself. This ensures that the data is written to the correct location within the file. Therefore, the statement is true.Rate this question:

S9(7) COMP-3 field occupy _________ bytes.
- A.
4
- B.
6
- C.
8
- D.
1
Correct Answer
A. 4Explanation
The S9(7) COMP-3 field is a packed decimal field that occupies 4 bytes. Packed decimal fields store numeric values in a compressed format, where each digit is represented by a nibble (half a byte). The S9(7) format indicates that the field can store up to 7 digits, including the sign. Since each digit requires a nibble, and there is an additional nibble for the sign, the total number of nibbles required is 8. However, since a nibble is half a byte, the field occupies 4 bytes.Rate this question:

- B.
REDEFINES
- C.
USAGE
- D.
SIGN
Correct Answer
B. REDEFINESExplanation
The correct answer is "REDEFINES". In COBOL programming, the REDEFINES clause is used to allow a data area to be referred to by more than one data name with different sizes and pictures. This allows for efficient memory usage and flexibility in accessing and manipulating data.Rate this question:

A data name gives references to the storage space to the memory where the actual value is stored.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A data name is a variable or identifier that is used to refer to a specific location in the computer's memory where a value is stored. This allows programmers to easily access and manipulate the stored value by using the data name. Therefore, the statement "A data name gives references to the storage space in the memory where the actual value is stored" is true.Rate this question:

. If A=10, B=20, C=30,D=0 Then the result of operation ______________ ADD A B TO C GIVING D
- A.
60
- B.
50
- C.
20
- D.
10
Correct Answer
A. 60Explanation
The given operation is "ADD A B TO C GIVING D". According to this operation, the values of A and B are added together and the result is stored in C. Since A=10 and B=20, the sum of A and B is 10+20=30. Therefore, the value of C becomes 30. The "GIVING D" part of the operation indicates that the result is also stored in variable D. So, the value of D is also 30. Hence, the correct answer is 60.Rate this question:

What is the difference between COMP & COMP-3?
- A.
Binary format,
- B.
packed decimal format
- C.
packed decimal format & binary format,
Correct Answer
C. packed decimal format & binary format,Explanation
The difference between COMP and COMP-3 is that COMP uses binary format to store numeric values, while COMP-3 uses packed decimal format. In binary format, each digit of the number is represented by a series of 0s and 1s, allowing for efficient storage and arithmetic operations. On the other hand, packed decimal format stores each digit of the number in a separate nibble, with the sign stored in the last nibble. This format is more space-efficient but requires additional processing to perform arithmetic operations.Rate this question:

Which of the following is false among the statements?
- A.
77 level used for elementary level item
- B.
88 level used for condition.
- C.
77 level can be sub divided themselves
- D.
66 level used for RENAMES clause
Correct Answer
C. 77 level can be sub divided themselvesExplanation
The statement "77 level can be sub divided themselves" is false. In COBOL, the 77 level is used to define elementary level items, which cannot be further subdivided. The 77 level is typically used to declare variables or data items that hold simple values like numbers or characters. On the other hand, higher levels like 88 and 66 can be used to define conditions or aliases for other data items.Rate this question:

A ____means the specific value which remains unchanged throughout the execution of program.
- A.
LITERAL
- B.
GLOBAL
- C.
STOP RUN
Correct Answer
A. LITERALExplanation
A LITERAL means the specific value which remains unchanged throughout the execution of the program. In programming, a literal is a value that is directly written into the code and does not change during runtime. It is used to represent fixed values such as numbers, characters, or strings. LITERALS are often used to assign initial values to variables or as operands in expressions. They are not affected by any calculations or operations performed in the program and remain constant throughout its execution.Rate this question:
