What is RPG free?
RPG Free (also known as RPGLE Free-Format) is a modern syntax for the RPG programming language, primarily used on IBM i (AS/400) systems. It allows developers to write RPG code with a more streamlined and readable syntax, reducing the reliance on fixed column positions that were characteristic of older RPG versions. RPG is a stable programming language mainly because of its proprietary origin (IBM developed it). It is also a mature programming language, having gone through decades of testing, updates, and enhancements since its first inception more than 6 decades ago.
