Hi All, To preface my question, yes, there have been many past discussions about the hazards and drawbacks of using various popular programming languages,...
Hi Peter, A key characteristic of MDA models is that they are semantically machine readable and are transformed to implementation. For xUML models this...
... I've done a similar thing, but using Smalltalk. ... If you have the Smalltalk debugger and development environment, then I think you wouldn't miss the ...
Responding to N.... The main reason one wants to use an AAL is to have a consistent level of abstraction for the models. UML with an AAL is a true 4GL while...
Hi Peter, ... Good move! ... I suppose it depends on your purpose. There are many action languages, but they are merely a textual representation of some model...

Hi Yanni - Thanks for the response. I'm a lot more clear on where you're coming from now. Seems like a relative expert finding a blend of something close and...
Responding to Chiu... ... Alas, by that argument everyone would still be programming in machine language on plug boards. B-) I can remember the hard core BAL...

Hi Peter N., Thanks for the extended reply. What I got from your last message is: - Python - as a dynamic language - is far better suited for adaptation as a...
Responding to Chiu... ... I was responding to the notion that one /needs/ the 3GL facilities to develop an application. As I indicated, the only reason I see...
Responding to N.... I addressed the issue of whether one /needs/ more control of the implementation that the existing AALs provide with Chui, so I won't repeat...
