{{stub}}{{language|S-BASIC}} S-BASIC (the S stands for "structured") was a native-code compiler for an ALGOL-like dialect of the BASIC programming language, and ran on 8-bit microcomputers using the Z80 CPU and the CP/M operating system. (There are a number of CP/M or Z80 emulators that will allow the compiler to run on Windows or Linux systems.) The language and the compiler were developed during the period 1979-1981 by Gilbert Ohnysty, who saw a need for a true native-code compiler and a language implementation that preserved BASIC's ease of use and straight-forward syntax, while incorporating the syntactic and control-flow features associated with modern programming languages.
