I imagine you'd have to get all 3 of them .
The kbc would be the language itself.
the kbide would be your IDE (Integrated Development Environment)
kbrun would be your runtime and interpreter for yor programs to actually run. This interprets the code provided by the kbc and translates it into something the linux system can understand.
You cannot put anything into kdevelop. (well, technically taht's wrong.. but that's a whole nother discussion)
your IDE has the compiler...
But then again, I've never done a BASIC programming... so I'm just shooting in the air here...
That's why I've gone gambas
No ... but seriously... if you want pure basic dude, you may be out of luck here... I know that's not what you wanted to find out, but put BASIC is just not the most common language in linux.
I'd migrate to somethin glike mono-VB or gambas since the syntax is really next to the same... or find a way to run VB in wine.
The problem with running VB under wine is that ... well.... You'll be developing windows software... which is not good in linux.
