In the 1980’s and 1990’S the source code editor was a text based green screen tool (PDM/SEU) which is still in use at AHP today. This text based editor does not syntax check any of the new programming languages nor does it allow more than 20 lines of source code to be displayed at any time. In the late 1990’s SEU was replaced by the new generation of Windows based program code editors. The early version of the code editor was the Websphere Developer Studio (WDSc) and was re-branded Rational Developer for IBM i (RDi) a few years later.
The short answer to “why use RDi” can be summarized as:
Rational Developer for i is intended for IBM i application programmers or analysts who want to start using modern, more productive development tools. It is the industry standard alternative to the text-based user interface PDM/SEU toolset, providing easier ways to perform everyday tasks. In addition to all PDM functionality, the RSE also includes a number of enhancements that are not available in PDM/SEU:
Once an RPG developer uses RDi, speed of programming and speed of problem resolution drastically increases. Quality of Code is drastically increased. Not to mention the fact that the programmer will find him/herself being naturally draw into the world of modern programming, naturally embracing new coding techniques and improvements. I am not a lone voice in the darkness, here are recent web articles and blogs from industry pundits (non-IBMers) that deal with the same issue.
