In this project you will learn to process data records in a sequential file using COBOL. You will code, compile, and run programs that add new records to an existing file and modify individual data values on existing file records. Your hands-on practice will take place in the PC-based OpenCobolIDE application.

Skills you will develop

  • OpenCobolIDE

  • Sequential file

  • Record processing

  • coding

  • COBOL Programming

Learn step-by-step

In a video that plays in a split-screen with your work area, your instructor will walk you through these steps:

  1. Discuss sequential file concepts as you review the data files used in this project by running COBOL programs in OpenCobolIDE.

  2. Write the File-Control section and the FD that provides a file name and file format in a COBOL program that adds a record to a sequential file.

  3. Write the COBOL code to prompt a user for data values and then write those data values to a new record in a sequential file.

  4. Compile a completed COBOL program and run the executable to test the results to confirm that one or more records are added correctly to a sequential file.

  5. Complete and test a COBOL program that prompts a user for a data value for a specific record, locates that record, and then modifies the value.
