Chapter To familiarize you with  Why COBOL is a popular business-oriented language.  Programming practices and techniques  History of COBOL.

Introduction to COBOL. COBOL  COBOL is an acronym which stands for Common Business Oriented Language.  The name indicates the target area of COBOL applications.

PROCEDURE DIVISION. MAINLINE. PERFORM A-100-INITIALIZE. PERFORM B-100-PROCESS. PERFORM C-100-TERMINATE. STOP RUN. Scrntest.cbl Header information displayed at the top of the screen. Detail information displayed on the current line. Note that CUR is set to 4 and will be incremented so the first line is displayed on line 5. This structure allows the programmer to display multiple copies of INFO- SCR-IN. The user will enter either C to continue or Q to quit when the RESP-INFO portion of the screen is displayed.

DISPLAY INFO-SCR-IN. READ INPUT-FILE AT END MOVE "YES" TO EOF-IND. C-100-TERMINATE. CLOSE INPUT-FILE. Scrntest.cbl Displays the header information on the screen. Performs the routine which will put up the repeating lines of information until either CT which counts the record is greater than 4, or EOF is reached or the user quits. In this B-300-SETUP loop,1 is added to the current line, CUR and to the CT which is counting the records. Then the information is displayed and another record is read. When the B-300-SETUP loop is finished, the response screen is displayed and the user response is accepted. This ends the pass through the B-200-LOOP,
