Yabasic
Yabasic (Yet Another BASIC) is a free and open source BASIC interpreter for Windows and Unix platforms. Yabasic was originally developed by Marc-Oliver Ihm, who released the last stable version 2.769 in 2015. As a continuation of the project, version 3 was being developed by a team centered on Pedro Sá and Thomas Larsen, but development slowed and the project now appears to be abandoned.
