BASIC-11 [1] [2] [3] was a dialect of the basic language for PDP-11 operating systems such as RSX-11, RT-11, TSX and TSX-Plus. [4] It was a classic BASIC in that it used line numbers, supported line number editing, and classic function syntax. It provided extended support for user-defined functions, external sequential disk files, and linking with assembler language modules for device support and operating system interfaces.
Digital Equipment Corporation, using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until he was forced to resign in 1992, after the company had gone into precipitous decline.
The PDP–11 is a series of 16-bit minicomputers sold by Digital Equipment Corporation (DEC) from 1970 into the late 1990s, one of a set of products in the Programmed Data Processor (PDP) series. In total, around 600,000 PDP-11s of all models were sold, making it one of DEC's most successful product lines. The PDP-11 is considered by some experts to be the most popular minicomputer.
RSX-11 is a discontinued family of multi-user real-time operating systems for PDP-11 computers created by Digital Equipment Corporation. In widespread use through the late 1970s and early 1980s, RSX-11 was influential in the development of later operating systems such as VMS and Windows NT.
RT-11 is a discontinued small, low-end, single-user real-time operating system for the full line of Digital Equipment Corporation PDP-11 16-bit computers. RT-11 was first implemented in 1970. It was widely used for real-time computing systems, process control, and data acquisition across all PDP-11s. It was also used for low-cost general-use computing.
Microsoft BASIC is the foundation software product of the Microsoft company and evolved into a line of BASIC interpreters and compiler(s) adapted for many different microcomputers. It first appeared in 1975 as Altair BASIC, which was the first version of BASIC published by Microsoft as well as the first high-level programming language available for the Altair 8800 microcomputer.
OS/8 is the primary operating system used on the Digital Equipment Corporation's PDP-8 minicomputer.
RSTS is a multi-user time-sharing operating system developed by Digital Equipment Corporation for the PDP-11 series of 16-bit minicomputers. The first version of RSTS was implemented in 1970 by DEC software engineers that developed the TSS-8 time-sharing operating system for the PDP-8. The last version of RSTS was released in September 1992. RSTS-11 and RSTS/E are usually referred to just as "RSTS" and this article will generally use the shorter form. RSTS-11 supports the BASIC programming language, an extended version called BASIC-PLUS, developed under contract by Evans Griffiths & Hart of Boston. Starting with RSTS/E version 5B, DEC added support for additional programming languages by emulating the execution environment of the RT-11 and RSX-11 operating systems.
TOPS-10 System is a discontinued operating system from Digital Equipment Corporation (DEC) for the PDP-10 mainframe computer family. Launched in 1967, TOPS-10 evolved from the earlier "Monitor" software for the PDP-6 and PDP-10 computers; this was renamed to TOPS-10 in 1970.
DIBOL or Digital's Business Oriented Language is a general-purpose, procedural, imperative programming language that was designed for use in Management Information Systems (MIS) software development. It was developed from 1970 to 1993.
TSX-Plus is a multi-user operating system for the PDP-11/LSI-11 series of computers. It was developed by S&H Computer Systems, Inc. and is based on DEC's RT-11 single-user real-time operating system.
FOCAL is an interactive interpreted programming language based on JOSS and mostly used on Digital Equipment Corporation (DEC) Programmed Data Processor (PDP) series machines.
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). It was originally developed as BASIC-PLUS in the 1970s for the RSTS-11 operating system on the PDP-11 minicomputer. It was later ported to OpenVMS, first on VAX, then Alpha, and most recently Integrity.
On-line Debugging Tool (ODT) is a family of several debugger programs developed for Digital Equipment Corporation (DEC) hardware. Various operating systems including OS/8, RT-11, RSX-11, and RSTS/E implement ODT, as did the firmware console of all of the LSI-11-family processors including the 11/03, 11/23/24, 11/53, 11/73, and 11/83/84.
The Gold key is a computer keyboard key used as a prefix to invoke a variety of single-key editing and formatting functions. Usually located in the top-left position of the numeric keypad on platforms such as the VT100, it is the signature element of a consistent user interface implemented by Digital Equipment Corporation (DEC) across multiple product lines.
Multi-user BASIC was a dialect of the BASIC language for the DEC PDP-11 running the RT-11 operating system. One or more users were supported in separate address spaces sharing the same language interpreter. The syntax of the language was similar to but not identical to BASIC-11. A key language element was the support for virtual files. These were similar to the virtual arrays in BASIC-PLUS in but more limited. An array of integers, floating-point, or character strings of length 1, 2, 4, 8, 16, 32, or 64 could be placed in file and accessed with a subscript. The file could actually be opened with a different definition allowing integers, characters, and floating point numbers to be stored in the same file.
TSX-32 has been a general purpose 32-bit multi-user multitasking operating system for x86 architecture platform, with a command line user interface. It is compatible with some 16-bit DOS applications and supports file systems FAT16 and FAT32. It was developed by S&H Computer Systems, and has been available since 1989.
TSS/8 is a discontinued time-sharing operating system co-written by Don Witcraft and John Everett at Digital Equipment Corporation in 1967. DEC also referred to it as Timeshared-8 and later the EduSystem 50.
Synergy DBL is a compiled, imperative programming language designed for business use. The language was originally called DBL; later it was referred to as Synergy Language; as of 2012 the official name is Synergy DBL. It is based on Digital Equipment Corporation’s DIBOL programming language.
Commercial Operating System (COS) is a discontinued family of operating systems from Digital Equipment Corporation.
Interactive Application System (IAS) was a DEC operating system for the PDP-11. It was a fork from RSX-11D.
