In line PERFORM work as long as there are no internal GO TOs, not even to an exit.ġ8) Which division and paragraphs are mandatory for a COBOL program? The PERFORM and END-PERFORM statements are used to block the cobol statements between them. It is part of a called program that maps to data items in the calling program’s working storage.ġ6) What are the access modes of START statement?Īccess modes are SEQUENTIAL or DYNAMIC for the start statement.Īn IN-LINE PERFORM Statement allows the routine being performed to be nested within the perform statement itself instead of being a seperate paragraph The linkage section is used to pass data from one program to another program or to pass data from a procedure to a program. In the OUTPUT PROCEDURE, output file is opened, the sorted record is returned to the Output record and then the record will be written. In the INPUT PROCEDURE, the input file is opened, records are read and edited and then are released to the sorting operation. It is defined in the DATA DIVISION after WORKING-STORAGE SECTIONġ4) What are INPUT PROCEDURE and OUTPUT PROCEDURE? Local-Storage is allocated each time the program is called and will be de-allocated when the program stops via an EXIT PROGRAM, GOBACK, or STOP RUN. Object Oriented Cobol language is a Natural way of programming in which you identify the objects, and then write functions and procedures around that object.
MICROFOCUS COBOL TUTORIAL PDF CODE
Structured programming is logical way of programming where the functionalities are divided into modules and helps write the code logically.
ON SIZE ERROR option is raised when there is REPLACING allows for the same copy to be used more than once in the same code by changing the replace value.ġ1) What kind of error is trapped by ON SIZE ERROR option? The range is executed at least once in TEST AFTER.ġ0) What is the point of the REPLACING option of a copy statement? If TEST AFTER is specified, the condition is tested at the end of the each repeated execution of the PERFORM range. If TEST BEFORE is specified, the condition is tested at the beginning of each repeated execution of the specified PERFORM range. The difference between EVALUATE and case is that ‘break’ is not used in Evaluate statement and the control comes out of the EVALUATE once a match is found.ĩ) What is the difference between PERFORM … WITH TEST AFTER and PERFORM … WITH TEST BEFORE? Dynamic and Static linking can be achieved by choosing either the DYNAM or NODYNAM link edit option.Ĩ) What is the use of EVALUATE statement?Įvaluate is just like a case statement or it can be used like a Nested IFs. In static linking, called subroutine links into the calling program, while in dynamic linking, the subroutine & the main program will exist as separate modules. PARAGRAPH will have only that paragraph to be performed.ĥ) What is the difference between CONTINUE & NEXT SENTENCE?ĬONTINUE is like a null statement and it continues execution, while NEXT SENTENCE transfers control to the next sentence.Ħ) What are the different OPEN modes available in Cobol?
SECTION will have all the paragraphs that are part of the section, to be performed. 4) What is the difference between performing a SECTION and a PARAGRAPH?
