Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. This free software for Mac OS X is an intellectual property of Mr.Kibernetik. The program lies within Developer Tools, more precisely Webmaster Tools.
From the developer:
BestBASIC is an upgraded classical minimal BASIC language. It keeps an attractive simplicity while adding such enhancements as graphics, files, interface objects, complex numbers and lots of other functions and advanced language syntax features. BestBASIC comes with sample programs and built-in language reference.
