COBOL Online Quiz
Following quiz provides Multiple Choice Questions (MCQs) related to COBOL Framework. You will have to read all the given answers and click over the correct answer. If you are not sure about the answer then you can check the answer using Show Answer button. You can use Next Quiz button to check new set of questions in the quiz.
Q 1 - What is the maximum size of a numeric field we can define in COBOL?
Answer : B
Explanation
COBOL applications use 31 digit numeric fields. However, compiler only supports a maximum of 18 digits. So we use a maximum of 18 digits.
Q 2 - Which utility is used for compiling COBOL program?
Answer : B
Explanation
IGCRCTL utility is used to compile a COBOL program.
Q 3 -How you will comment a line in a COBOL program?
A - Code asterisk(*) at 1st column.
B - Code asterisk(*) at 7th column.
Answer : B
Explanation
Coding asterisk (*) at 7th column comments out the complete line in COBOL program.
Q 4 - What is the output of the following code?
IDENTIFICATION DIVISION. PROGRAM-ID. HELLO. DATA DIVISION. WORKING-STORAGE SECTION. 01 WS-NUM1 PIC 9(9). 01 WS-NUM2 PIC 9(6). PROCEDURE DIVISION. A000-FIRST-PARA. MOVE 123456789 TO WS-NUM1. MOVE WS-NUM1(3:6) TO WS-NUM2. DISPLAY WS-NUM2 STOP RUN.
Answer : D
Explanation
WS-NUM1(3:6) indicates that select from 3rd column & up to 6 digits. So result will 345678.
You can try same code using Try it option available below:
IDENTIFICATION DIVISION. PROGRAM-ID. HELLO. DATA DIVISION. WORKING-STORAGE SECTION. 01 WS-NUM1 PIC 9(9). 01 WS-NUM2 PIC 9(6). PROCEDURE DIVISION. A000-FIRST-PARA. MOVE 123456789 TO WS-NUM1. MOVE WS-NUM1(3:6) TO WS-NUM2. DISPLAY WS-NUM2 STOP RUN.
Q 5 - What is the output of following program?
IDENTIFICATION DIVISION. PROGRAM-ID. HELLO. DATA DIVISION. WORKING-STORAGE SECTION. 01 WS-DESCRIPTION. 05 WS-DATE1 VALUE '20140831'. 10 WS-YEAR PIC X(4). 10 WS-MONTH PIC X(2). 10 WS-DATE PIC X(2). 05 WS-DATE2 REDEFINES WS-DATE1 PIC 9(8). PROCEDURE DIVISION. DISPLAY WS-DATE2. STOP RUN.
Answer : B
Explanation
When we redefine WS-DATE1 to WS-DATE2, automatically values from WS-DATE1 will be moved to WS-DATE2.
You can try same code using Try it option available below:
IDENTIFICATION DIVISION. PROGRAM-ID. HELLO. DATA DIVISION. WORKING-STORAGE SECTION. 01 WS-DESCRIPTION. 05 WS-DATE1 VALUE '20140831'. 10 WS-YEAR PIC X(4). 10 WS-MONTH PIC X(2). 10 WS-DATE PIC X(2). 05 WS-DATE2 REDEFINES WS-DATE1 PIC 9(8). PROCEDURE DIVISION. DISPLAY WS-DATE2. STOP RUN.
Q 6 - Search is a binary search method, which is used to find elements inside the table. Is this statement true or false?
Answer : B
Explanation
This statement is false as Search is a linear search method where as Search All is binary search method.
Q 7 - Static Call occurs when a program is compiled with the NODYNAM compiler option. A static called program is loaded into storage at compile time. Is this statement true or false.
Answer : B
Explanation
This statement is correct.
Q 8 - Which of the following is not a figurative constant?
Answer : B
Explanation
Comma is not a figurative constant. Figurative constants are constant values.
Q 9 - In which division we declare our variables?
Answer : C
Explanation
In Data Division we declare all the working storage variables.
Q 10 - Elementary items cannot be divided further. Level number, Data name, Picture clause and Value clause (optional) are used to describe an elementary item. State whether true or false?
Answer : A
Explanation
This statement is correct.
