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.

Habilidades que desarrollarás

  • Sequential file
  • Record processing
  • coding
  • COBOL Programming

Aprende paso a paso

En un video que se reproduce en una pantalla dividida con tu área de trabajo, tu instructor te guiará en cada paso:

  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.
