COBOL is a programming language that serves a wide range of businesses. Key aspects of COBOL are that it is scalable, mature, and self-documenting. In this COBOL CORE class you’ll discover more features of the language, how to handle tables, edit, use switches, numeric usage, and structured COBOL. Enjoy your ride through the world of COBOL! We’re excited to have you here and can’t wait to get started.

Syllabus

Introduction to COBOL Core

Welcome to COBOL Core. In this first module, we will explore some basic concepts and preview how the IBM Remote Lab Platform (IRLP) labs will work.

Numeric usage Types, Editing and Branching

Great to see you in Module 2! Labs are what make this course essential training, and in Module 2 you'll experience one session to get familiar with the Skytap and the IRLP, and then a lab session dedicated to Numeric Usage Types. This week we look at 3 levels of Editing and Branching. This is the most intensive module in the course, because we've created several opportunities for you to work with hands-on labs and review the demonstrations carefully. Pace yourself, and don't worry if this one takes a little more than a week!

Structured Programming, Testing, Debugging, and Reports

We will discuss structured programming, testing, debugging, and reports, including, defining a calling program and called program, describing types and components of reports, listing steps for proper testing and strategies, recognizing and correcting unstructured code, describing the components of structured programming, and creating readable and maintainable code.

Table Handling, Sorting, and Intrinsic Functions

In the third module of this course, we will discuss table handling, sorting, and intrinsic functions, including, listing six types of intrinsic functions, describing the sort/merge process, using three examples of sequential search, and describing basic table terminology.
