I think one of the best BASIC's for Windows and Wine now that Bill gates has messed up Visual Basic with that .NET nonsense is a little shareware version called LibertyBASIC found at:
www.libertybasic.com
I was considering not buying Crossover for now when the demo would not run my old versions of this. But after getting the new version at the site above I found out that it runs great under Crossover with the exeception of a few problems running the more graphical sample programs. (was still a little bit on the skeptical side because LibertyBASIC 4.3 has a reputation for running but very slowley under free Wine.)
I also found that Crossover runs another programing software (Borland Delphi version 3) that I like and NoteWorthy composer (recognises my hardware MIDI based sound card and that's probably why I'm not expereincing the problems others have with this.
I basically Bought a CrossOver Licence today based on these three programs but I'm also experimenting with Windows Shareware card games (Cards is mo favorite type of computer game.) and other Windows programs I have in my pre Linux software library. Of those one, (The Real Deal) failed in such a way I had to log out of KDE and start over again. (Produced a dialog of virtually infinite width with no button to cancel it.) other card games appear to be working fine however.
More later, as you can se I'm an experimenter and will continue to report on my successes and failures in Crossover/Wine.
So far the successes are:
Borland Delphi Standard version 3
LibertyBASIC version 4.3
NoteWorthy Composer
SAC Win-Pinochle
The Failures are
Borland C++ Builder Standard version 5
The Real Deal (Card games suite)
PowerBASIC all versions tested (Console Compiler 3.0* and Windows ver 7.0)
*Power Basic Console Compiler also requires wineconsole to to see ececutables which is not available in Crossover and is buggy in almost all versions of free Wine in addition to being a non working app anyway. The libertyBASIC that started this post does not have this problem because it has a "Console" window of its own for text mode apps.
