BASIC is a programming language designed by John G. Kemeny and Thomas E. Kurtz in 1964. It was introduced on OpenVMS in 1980 as BASIC Multikey ISAM for VMS 2.0. The latest version of BASIC for OpenVMS, VSI BASIC, is a shareable language processor for the OpenVMS operating system. It can be invoked as a compiler and the resulting modules can be linked and run with standard OpenVMS commands. VSI BASIC provides high performance for application development by generating inline native mode instructions. VSI BASIC is also integrated with various programming productivity tools such as the OpenVMS Debugger, the Language-Sensitive Editor (LSE), the Source Code Analyzer (SCA) and the |Performance and Coverage Analyzer.
