google translation helped me to understand what you are talking about.
Well I recently re-visited VisualAge for Basic for OS/2. It is not perfectly stable and no longer maintained.
Its features are almost equal to VB 3.
This is nothing one could consider a suitable programming language or environment for todays programming tasks.
However, it still has a lot of stuff which is not available in rexx. Especially "nice" printing functions.
On the other hand, if someone wants to have plattform independent development, even REXX starts to become problematic, especially when doing GUI programming with it. Perhaps one day "dynamic windows" (netlabs) will provide us a DLL for REXX that is stable and mature... it only would need a graphical development environment to simplify drawing GUIs.
Then on the other hand again, I would prefer to have the QT GUI controls available for rexx on OS/2... but they are working on QT4 porting, not focusing on making QT available to rexx at all.
I guess if you really want platform independent development, you have to go Java.
Then again, see how old the OS/2 Java is.
