COBOL - Interview questions
Dear readers, this one COBOL interview questions have been specifically designed to provide you with the type of questions you will encounter during your interview for the topic of the encounter COBOL programming language . In my experience, good interviewers hardly plan to ask a specific question during your interview. Usually questions start with some basic concept of the subject and later they will continue based on further discussion and what you answer:
A: COBOL stands for Common Business Oriented Language. The US Department of Defense, in a conference, formed CODASYL (Conference on Data Systems Language), a language to develop corporate computing requirements that is known today as COBOL.
A:COBOL is a standard language that can be compiled and run on different machines. It is ideally suited for business-oriented applications as they process large amounts of data. It has numerous bedugging and testing tools. COBOL is a structured language; it has different divisions so it is easy to debug.
A:Identify divisions, neighborhood divisions, data divisions, and procedure divisions.
A: alphanumeric (X), in alphabetical order (A), and numeric (9).
A: is numeric clause is used to check whether an item is numeric or not. It returns TRUE if the element on which it is used contains only numbers (0 to 9). The element can be positive or negative.
A: Level 66 is used for RENAMES clause and level 88 is used for condition names.
A: The subscript is the occurrence in an array. Index corresponds to the displacement from the beginning of an array.
A: SEARCH is a serial search, whereas SEARCH ALL is a binary search. A table must be in sorted order before using SEARCH ALL. .
A: PERFORMING A SECTION will cause all paragraphs that are part of the section to be performed. Performing a paragraph causes only one digit to be performed.
A: Scope terminator is used to mark the end of a verb. Example:. IF and END-IF.
A: File open modes in COBOL include. INPUT, OUTPUT, IO and EXTEND.
A: The maximum size of a numeric field is PIC 9 (18).
A: NEXT transfers control to the next statement after the scope terminator. Next record transfers control to the instruction after the first period has resulted.
A: 01 is worth the record. We repeat the fields within a record, the record itself. Such a step clause cannot be used in 01-level.
A: to write to a file to open either OUTPUT or EXTEND mode are over the file.
A: The parameters are transferred in a call-by-content to protect them from changes made by the called program. When called via reference, parameters can be changed by the called program.
A:The link section is a part of a program called that "links" or maps to data items in the calling program's memory.
A: the program will go in an endless loop.
A: It is stored in the last nibble.
A: Comp is a binary usage while comp-3 gives packed decimal number.
A: Identification Division used for documentation purposes.
A: In static call, the called program becomes a stand-alone program, it is an executable program. During the runtime we can call it up in our named program. As with dynamic calling, the called program is not an executable program; it can only be executed by the named program.
A: Defined clause is used to allow the same memory usage to be referenced by different data names.
A: The purpose of the pointer term is to indicate the leftmost position within the recording field where the first over characters are to be placed.
A: It is an elementary level article that cannot be subdivided.
A: Compare the item with the item being searched in the middle. If it is okay, depending on where the element is located, otherwise repeat the process with the left half and right half.
A: Evaluate is like a case statement and can be used to replace nested ifs. No pause is required as control comes as soon as a match is found.
A: Yes, Redefine causes both fields to start in the same place.
A: COMP-1 is a single precision floating point number that uses 4 bytes. COMP-2 is a double precision floating point that uses 8 bytes.
A: Take verb is used to get data such as date, time and day from the operating system or directly from the user. When a program accepts data from the user, it must be passed through the JCL.
A: Compute statement is used to write arithmetic expressions in COBOL. This is a substitute for adding, subtracting, multiplying, and dividing.
A: Supply the DD cards in JCL as it is designated for the files in the main program.
A: Identification Division and Program-Id paragraph are mandatory in a COBOL program.
A: Area B starts from 12 to 72 columns.
A: It appears in the input-output section in the Environment Division.
A: If TEST BEFORE is specified, the condition is tested at the beginning of each repeated execution of the specified PERFORM range. If TEST AFTER is specified, the state is tested at the end of each repeated execution of the PERFORM area. The area will be run at least once in the test after.
A: Local storage is assigned every time a program is called and will be de-assigned when the program stops via an EXIT PROGRAM, GOBACK or STOP RUN. It is defined in the DATA DIVISION according to the WORKING-STORAGE SECTION.
A: The access modes are SEQUENTIAL or DYNAMIC for the start statement.
A: PIC 9.99 is a four position field that actually contains a decimal point, where as PIC 9v99 on three position number field with an assumed decimal place.
A: No, the table must be indexed in order to search on a table.
A: Before REWRITE is performed, the record must be opened and read from the file. Therefore, the file must be opened in IO mode for rewrite functionality.
A: A literal is an item of data that is worth by itself. It cannot be denoted by a name. They are constant data articles.
What is now?
Additionally, you can go through the examples that you have practiced on the subject and make sure that you are able to speak on them confidently. If you're fresher, then the interviewer doesn't expect you to answer very complex questions, and doesn't make your basics very strong. .
It's really not much if you can't answer a few questions, but it's important how you answered the ones you did. So just be confident during your interview. We at tutorialspoint give you all the best ..
