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:
- Improve developer productivity
- Common development tools platform
- Improve developers skills
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:
