Dav (Tue Dec 2 2008 at 7:24 am) QB64 Project added to links. Check it out.
QB64 is a one-man project, by 'Galleon', attempting to make a FREE Qbasic syntax compiler for windows that create EXE compiled programs which will run on modern computers.
QB64 coming along nicely, and it may already be the most Qbasic compatible compiler on the planet. An IDE will be released soon.
