In this project you will use COBOL code to read the data records from a sequential file. You will code, compile, and run programs using the PC-based COBOL IDE called OpenCobolIDE. Since COBOL is often used with large amounts of data, the ability to process files—to read the records in them as input and write the records as output—is a critical skill for any COBOL programmer.

About this Guided Project
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:
Examine a sample sequential file as you observe how it is used to organize data and learn the associated terminology.
Code the COBOL FD statement in the File section of the Data Division to describe the fields that make up a record within a sequential file used as input.
Add, compile, and run the code in a COBOL program’s Procedure Division to read through the records in a sequential input file and then display the fields from each record on the screen.
Define the layout of an output file in a COBOL program Data Division’s File section by describing the fields and data types that make up each record.
Add, compile, and run COBOL code that moves data from the input record to the output record and generates a sequential file as output.
Recommended experience
Ability to navigate in Windows is required. Although prior exposure to COBOL is not required, it would be helpful.
