wikipedia org wiki superbasic superbasic from wikipedia the free encyclopedia jump to navigation jump to search this article is about the interpreter included in sinclair qdos for the unrelated basic system by tymshare see super basic superbasic is an advanced variant of the basic programming language with many structured programming additions it was developed at sinclair research by jan jones during the early 1980s originally superbasic was intended as the basic interpreter for a home computer code named superspectrum then under development this project was later cancelled however superbasic was subsequently included in the rom firmware of the sinclair ql microcomputer announced in january 1984 also serving as the command line interpreter for the ql s qdos operating system it was one of the first second generation basics to be integrated into a microcomputer s operating system unlike bbc basic which preceded it in 1981 making the os user extendable as done by linus torvalds in his formative years contents 1 advanced features 2 example 3 bibliography 4 references 5 external links advanced features edit respr for resident procedures e g to extend qdos choice of
