Getting Started: Free vs. Fixed and Internal Documentation in ILE RPG Programming

Part three of getting started ILE RPG program addresses free vs. fixed and internal documentation. Read parts one and two here: Getting Started: Sections & a Sample of ILE RPG Programs and here: Getting Started: Building the ILE RPG Program and Navigating Legacy Code

By Brian Meyers and Jim Buck

Editor's Note: This article is excerpted from chapter 2 of Programming in ILE RPG, Fifth Edition.

Free vs. Fixed

As you can see, RPG’s free-format instructions have a more consistent, modern layout than do the fixed-format equivalents. If you are using free format, you’ll probably find it easier to concentrate on your program’s logic instead of its exact positional syntax. In addition, free-format operations allow you to use indentation to visually explain blocks of related code. You don’t need to remember which operation codes support which C-spec layout if you are using free format.

The Power of Writing Code in a Low-Code Solution

When it comes to creating your business applications, there are hundreds of coding platforms and programming languages to choose from.

By LANSA, an Idera, Inc. Company

Editor's Note: This article is excerpted from the white paper, The Power of Writing Code in a Low-Code Solution available for download in the MC Press White Paper Center.

These options range from very complex, traditional programming languages to low-code platforms where sometimes no traditional coding experience is needed. Low-code platforms range from not using a programming language at all to using a very detailed programming language to supplement the low-code functionality.

A detailed guide for knowing the difference in the platforms and when to use which one can be found here. Traditional programming languages provide great power and flexibility but at the cost of complexity and time. Enterprises are looking for a faster way to get new applications to market, and that’s where low-code development platforms come in.
