10
- B.
20
- C.
00
- D.
30
Correct Answer
C. 00Explanation
The output stored in variable WS-NUM3 is "00". This is because the value of WS-NUM1 is 100, and it is moved to WS-NUM3. Then the value of WS-NUM2 is moved to WS-NUM3, which overwrites the previous value. Since WS-NUM2 has a value of 200, the final value of WS-NUM3 becomes "00".Rate this question:

Correct Answer
B. B).4Explanation
The WORKING-STORAGE SECTION is used to declare variables and data structures that are used within the program. In this case, the variable WS-NUM1 is declared with a PICTURE clause specifying that it is a signed numeric field with 3 digits and the sign is leading separate. In COBOL, each digit occupies one byte of storage, and the sign takes up an additional byte. Therefore, WS-NUM1 will occupy 4 bytes in total.Rate this question:

6).OCCURS CAN BE DEFINED IN 01 LEVEL NO .TRUE OR FALSE?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement "OCCURS CAN BE DEFINED IN 01 LEVEL NO" is false. In COBOL programming, the OCCURS clause is used to define arrays or tables, and it can be defined at the 01 level or any other level in the data division. Therefore, the correct answer is false.Rate this question:

INDEX NAME SHOULD BE DEFINED IN WORKING-STORAGE SECTION?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The index name does not need to be defined in the working-storage section. In COBOL, the index name is typically defined within the procedure division using the INDEXED BY phrase in the OCCURS clause of a table declaration. This allows the index to be associated with a specific table and used for accessing and manipulating data within that table. Therefore, the correct answer is false.Rate this question:

Correct Answer
C. C).0Explanation
The value of WS-NUM1 is initially set to 1 in the working-storage section. Then, in the procedure division, the value of WS-NUM1 is changed to 5 using the MOVE statement. After that, the program enters a loop where it performs the 2100-PARA section until WS-NUM1 is less than 4. However, since the value of WS-NUM1 is already 5, the loop condition is not met and the 2100-PARA section is not executed at all. Therefore, the answer is C).0Rate this question:

WORKING-STORAGE SECTION. 01 WS-NUM1 PIC S9(7)V9(4) COMP-3. HOW MANY BYTES WS-NUM1 FIELD WILL OCCUPY?
- A.
A).11
- B.
B).6
- C.
C).5
- D.
D).8
Correct Answer
B. B).6Explanation
The WS-NUM1 field is defined as PIC S9(7)V9(4) COMP-3, which means it is a signed numeric field with a total length of 6 bytes. The "S" indicates that it is a signed field, the "9(7)" indicates that it can hold up to 7 digits before the decimal point, the "V" indicates the presence of a decimal point, and the "9(4)" indicates that it can hold up to 4 digits after the decimal point. The COMP-3 attribute indicates that it is a packed decimal representation, which requires half a byte for each digit and an additional half byte for the sign. Therefore, the WS-NUM1 field will occupy 6 bytes in total.Rate this question:

Can I redefine an X(200) field with a field of X(100) ?
- A.
A).YES
- B.
B).NO
- C.
C).NOT POSSIBLE
- D.
D).NONE
Correct Answer
A. A).YESExplanation
Yes, it is possible to redefine an X(200) field with a field of X(100). The "redefine" statement in programming allows for the reuse of memory space by defining a new field with the same starting location as the previous field. In this case, the X(100) field can be defined to start at the same location as the X(200) field, effectively redefining it.Rate this question:

). How many times PARA-1 is executed when SUB is with PIC 9. PERFORM PARA-1 VARYING SUB FROM 1 BY 1 UNTIL SUB = 10. PARA-1. DISPLAY SUB.
- A.
10 times
- B.
9 times
- C.
Keep looping (as SUB WILL BECOME 0 WHEN INCREASED TO 10)
- D.
None of these
Correct Answer
C. Keep looping (as SUB WILL BECOME 0 WHEN INCREASED TO 10)Explanation
The PERFORM statement in the given code is a loop that executes the PARA-1 paragraph multiple times. The VARYING clause is used to increment the SUB variable from 1 by 1 until it reaches 10. Therefore, the PARA-1 paragraph will be executed 10 times. The answer "Keep looping (as SUB WILL BECOME 0 WHEN INCREASED TO 10)" accurately describes the behavior of the loop.Rate this question:

01 WS-NUM1 PIC 9(2). 01 WS-NUM2 PIC 9(2). PROCEDURE DIVISION. MOVE 10 TO WS-NUM1,WS-NUM2 IF WS-NUM1 = WS-NUM2 CONTINUE ELSE DISPLAY ‘TWO NO ARE NOT EQUAL’ END-IF. DISPLAY ‘TWO NO ARE EQUAL’ WHAT IS THE OUTPUT OF THE ABOVE CODE?
- A.
TWO NO ARE NOT EQUAL
- B.
TWO NO ARE EQUAL
- C.
NONE
- D.
NOTHING WILL DISPLAYED
Correct Answer
B. TWO NO ARE EQUALExplanation
The output of the above code will be "TWO NO ARE EQUAL". This is because the code first moves the value 10 to both WS-NUM1 and WS-NUM2 variables. Then it checks if WS-NUM1 is equal to WS-NUM2. Since both variables have the same value of 10, the condition is true and the code will display "TWO NO ARE EQUAL".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
The explanation for the given correct answer is that in a WRITE statement, it is necessary to specify the name of the record that is being written, rather than the name of the file. The WRITE statement is used in programming languages to write data into a file, and it requires the record name to identify the specific record that is being written. The file name is typically specified separately when opening or accessing the file. Therefore, the statement that it is required to mention the record name and not the file name in a WRITE statement is true.Rate this question:
