It has also been ported to a succession of new platforms as they were developed by DEC, Compaq, HP and VSI. The VSI BASIC for OpenVMS product history spans a period of more than 30 years, and it has gone through many name and ownership changes in that time. Before the release VAX BASIC, native RMS support was only available in DEC's COBOL compiler. One of VSI BASIC's more noteworthy features is built-in support for OpenVMS's powerful Record Management Services (RMS). The more traditional but less elegant "ON ERROR" statement lacks such context or scope. It allows you to write "WHEN ERROR" error handlers around protected statements. Line numbers are optional, unless the "ERL" function is present. VSI BASIC has many FORTRAN-like extensions, as well as supporting the original Dartmouth BASIC matrix operators.

Multiple variations of the titles noting the hardware platform (VAX, AlphaServer, etc.) also exist. Past names for the product include: BASIC-PLUS, Basic Plus 2 ( BP2 or BASIC-Plus-2), VAX BASIC, DEC BASIC, Compaq BASIC for OpenVMS and HP BASIC for OpenVMS. It was later ported to OpenVMS, first on VAX, then Alpha, and most recently Integrity. It was originally developed as BASIC-PLUS in the 1970s for the RSTS-11 operating system on the PDP-11 minicomputer. VSI BASIC for OpenVMS is the latest name for a dialect of the BASIC programming language created by Digital Equipment Corporation (DEC) and now owned by VMS Software Incorporated (VSI).
