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.

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.

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!

I would have benefited from a few more examples, e.g., how to subscript a 2-dimensional table, and an example or lab with both input and output phases. There were no examples of MERGE or its purpose.
