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:

  1. Review the OpenCobolIDE as you tour the user interface and open, compile, and run a COBOL program.

  2. Write a PERFORM TIMES loop in a COBOL program to repeat a block of code a specific number of times.

  3. Write and run COBOL code that includes a loop that repeats a block of code until a specific condition is met.

  4. Challenge Task

  5. Compare the PERFORM VARYING loop and the PERFORM UNTIL loop as you alter COBOL code by replacing PERFORM UNTIL with PERFORM VARYING.

  6. Demonstrate the process of reading and displaying each record in a file using a COBOL PERFORM UNTIL loop with the EOF (end-of-file) condition.

  7. Capstone Activity

Recommended experience

A very basic knowledge of COBOL code is recommended.
