Helping to keep fit during the crises, a dear friend of mine and long-time user of yabasic, Michael Cwikel, has created a program to help in recording your indoor-excercises, complete with detailed instructions. This might help to keep up or even increase your fitness during the current crisis !
Yabasic is a traditional basic-interpreter. It comes with goto and various loops and allows to define subroutines and libraries. It does simple graphics and printing. Yabasic can call out to libraries written in C and allows to create standalone programs. Yabasic runs under Unix and Windows and has a comprehensive documentation; it is small, simple, open-source and free.
