VSI Pascal


VSI Pascal is a Pascal and compiler that runs on OpenVMS for VAX systems, OpenVMS for AlphaServer systems, and OpenVMS for Integrity servers.. It was also supported under Tru64.
VSI Pascal is compatible with standardized unextended Pascal as well as Extended Pascal, with its own extensions. The compiler frontend is implemented in BLISS. The VAX compiler used its own code generator, whereas the Alpha and Itanium compilers use Digital's proprietary GEM backend.
