VSI Pascal (formerly HP Pascal for OpenVMS,[1] Compaq Pascal, DEC Pascal, VAX Pascal and originally VAX-11 Pascal[2]) is a Pascal and Extended Pascal compiler that runs on OpenVMS for VAX systems, OpenVMS for AlphaServer systems, and OpenVMS for Integrity servers.[3] It was also supported under Tru64.[4][5]
VSI Pascal is compatible with standardized unextended Pascal as well as Extended Pascal, with its own extensions. The compiler frontend is implemented in BLISS.[6] The VAX compiler used its own code generator,[7] whereas the Alpha and Itanium compilers use Digital's proprietary GEM backend.[6]
