From old RPG to modern RPGLE

Modernize AS400 RPG to IBM i RPGLE Come with me on an RPG journey from archaic 1980's style RPG 2 to modern 2021 style RPG ILE

Starting with some RPG2 Logic Cycle Code

A little polish takes us to RPG3 wider format

RPG400 - Enter the AS400 - no Bruce Lee

Setting RPG Free - RPG ILE Free Format Let's look at an older subfile code example written in RPGLE /Free I did not write this original code, but it's a reasonably good example and definitely a good example to break apart. copy/paste. compile and test. Let's dive in!

This lesson guides programmers through the process of modernizing Scott Klement's RPGLE copybooks, transitioning from fixed-column RPG to free-format RPGLE. Learn to analyze legacy copybook structures, convert fixed-format code to free-format syntax, and maintain functionality while leveraging modern RPGLE features. Topics include updating data structures, prototypes, and procedures, ensuring compatibility with existing applications, and applying best practices for cleaner, more maintainable code.

Learn to write and read text files in RPGLE on IBM i with this practical lesson. This guide uses clear examples from the provided source code. You will create an IFS text file, edit it, and read it back. Follow these steps to build your IBM i skills.

Let's take the column based RPGLE code and upgrade it to RPG Free.

Let's take the column based RPGLE code and upgrade it to RPG Free and then do some more minor tweaks to make it even more modern.
