DIBOL
DIBOL or Digital's Business Oriented Language is a general-purpose, procedural, imperative programming language, designed for use in Management Information Systems (MIS) software development. It has a syntax similar to FORTRAN and BASIC, along with BCD arithmetic. It shares the COBOL program structure of separate data and procedure divisions. Unlike Fortran's numeric labels (for GOTO), DIBOL's were alphanumeric; the language supported a counterpart to computed goto. History DIBOL was originally marketed by Digital Equipment Corporation (DEC) in 1970. The original version, DIBOL-8, was produced for PDP-8 systems running COS-300. The PDP-8-like DECmate II, supports the COS-310 Commercial Operating System, featuring DIBOL. DIBOL-11 was developed for the PDP-11 running COS-350 operating system. It also ran on RSX-11, RT-11, and from 1978 on RSTS/E. DIBOL-32 runs on VMS systems, although it can also be used on other systems through emulators. ANSI Standards were released ...

Synergy DBL
Synergy DBL (Data Business Language) is a Compiler, compiled, Imperative programming, 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. DBL has an English-like syntax that was designed to be self-documenting and highly readable, but not verbose. The language is Procedural programming, procedural and, since 2007 (version 9.1), Object-oriented programming, object-oriented. Support for Microsoft’s .NET Framework was added in 2010 (version 9.5). Code is split into two divisions (data and procedure) and uses a rigid hierarchy. The language includes a standard library consisting of 240 built-in subroutines and functions, 10 built-in classes, and 11 APIs that provide functionality such as access to XML from within DBL programs and sending and receiving data via Hypertext Tra ...

Commercial Operating System (COS)
Commercial Operating System (COS) is a discontinued family of operating systems from Digital Equipment Corporation. They supported the use of DIBOL, a programming language combining features of BASIC, FORTRAN and COBOL. COS also supported IBM RPG (Report Program Generator). Implementations The Commercial Operating System was implemented to run on hardware from the PDP-8 and PDP-11 family. COS-310 COS-310 was developed for the PDP-8 to provide an operating environment for DIBOL. A COS-310 system was purchased as a package which included a desk, VT52 VDT (Video Display Tube), and a pair of eight inch floppy drives. It could optionally be purchased with one or more 2.5 MB removable media hard drives. COS-310 was one of the operating systems available on the DECmate II. COS-350 COS-350 was developed to support the PDP-11 port of DIBOL, and was the focus for some vendors of turnkey software packages. Pre-COS-350, a PDP 11/05 single-user batch-oriented implementation was released; t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timeline Of Programming Languages
This is a record of notable programming languages, by decade. Prior to 1950 there were 8 unique programming languages, where 6 were unique languages and 2 were combinations of unique languages. By 1960 there were around 45-50 unique programming languages, though only 12 new unique languages (i.e. not relying of already existing programs). A unique programming language hasn't been developed since Swift in 2007. The newest language, Google's Carbon, is a combination of C++ and Rust. As of December 2022, 395 unique programming languages exist, of which 37 are not a combination of other languages and thus fully unique.

RSTS/E
RSTS () is a multi-user time-sharing operating system developed by Digital Equipment Corporation (DEC, now part of Hewlett-Packard) for the PDP-11 series of 16-bit minicomputers. The first version of RSTS (RSTS-11, Version 1) 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 (RSTS/E, Version 10.1) 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. Acronyms and abbreviations *BTSS (Basic Time Sharing System – never marketed) – The first name for RSTS. *CCL (Concise Comm ...

DECmate II
DECmate was the name of a series of PDP-8-compatible computers produced by the Digital Equipment Corporation in the late 1970s and early 1980s. All of the models used an Intersil 6100 (later known as the Harris 6100) or Harris 6120 (an improved Intersil 6100) microprocessor which emulated the 12-bit DEC PDP-8 CPU. They were text-only and used the OS/78 or OS/278 operating systems, which were extensions of OS/8 for the PDP-8. Aimed at the word processing market, they typically ran the WPS-8 word-processing program. Later models optionally had Intel 8080 or Z80 microprocessors which allowed them to run CP/M. The range was a development of the VT78 which was introduced in July 1977. VT78 Introduced in July 1977, this machine was built into a VT52 case and had an Intersil 6100 microprocessor running at 2.2 MHz. The standard configuration included an RX02 dual 8-inch floppy disk unit which was housed in the pedestal that the computer rested on. DECmate Introduced in 1980, ...

OpenVMS
OpenVMS, often referred to as just VMS, is a multi-user, multiprocessing and virtual memory-based operating system. It is designed to support time-sharing, batch processing, transaction processing and workstation applications. Customers using OpenVMS include banks and financial services, hospitals and healthcare, telecommunications operators, network information services, and industrial manufacturers. During the 1990s and 2000s, there were approximately half a million VMS systems in operation worldwide. It was first announced by Digital Equipment Corporation (DEC) as VAX/VMS (''Virtual Address eXtension/Virtual Memory System'') alongside the VAX-11/780 minicomputer in 1977. OpenVMS has subsequently been ported to run on DEC Alpha systems, the Itanium-based HPE Integrity Servers, and select x86-64 hardware and hypervisors. Since 2014, OpenVMS is developed and supported by VMS Software Inc. (VSI). OpenVMS offers high availability through clustering — the ability to distribute the ...

PDP-8
The PDP-8 is a 12-bit computing, 12-bit minicomputer that was produced by Digital Equipment Corporation, Digital Equipment Corporation (DEC). It was the first commercially successful minicomputer, with over 50,000 units being sold over the model's lifetime. Its basic design follows the pioneering LINC but has a smaller instruction set, which is an expanded version of the PDP-5 instruction set. Similar machines from DEC are the PDP-12 which is a modernized version of the PDP-8 and LINC concepts, and the PDP-14 industrial controller system. Overview The earliest PDP-8 model, informally known as a "Straight-8", was introduced on 22 March 1965 priced at $18,500 (). It used diode–transistor logic packaged on Flip Chip (trademark), flip chip cards in a machine about the size of a small household refrigerator. It was the first computer to be sold for under $20,000, making it the best-selling computer in history at that time. The Straight-8 was supplanted in 1966 by the PDP-8/S, which ...

DECSYSTEM-20
The DECSYSTEM-20 was a 36-bit Digital Equipment Corporation PDP-10 mainframe computer running the TOPS-20 operating system (products introduced in 1977). PDP-10 computers running the TOPS-10 operating system were labeled ''DECsystem-10'' as a way of differentiating them from the PDP-11. Later on, those systems running TOPS-20 (on the KL10 PDP-10 processors) were labeled ''DECSYSTEM-20'' (the block capitals being the result of a lawsuit brought against DEC by Singer, which once made a computer called " The System Ten"). The DECSYSTEM-20 was sometimes called PDP-20, although this designation was never used by DEC. Models The following models were produced: *DECSYSTEM-2020: KS10 bit-slice processor with up to 512 kilowords of solid state RAM (The ADP OnSite version of the DECSYSTEM-2020 supported 1 MW of RAM) *DECSYSTEM-2040: KL10 ECL processor with up to 1024 kilowords of magnetic core RAM *DECSYSTEM-2050: KL10 ECL processor with 2k words of cache and up to 1024 kilowords of R ...

DECsystem-10
Digital Equipment Corporation (DEC)'s PDP-10, later marketed as the DECsystem-10, is a mainframe computer family manufactured beginning in 1966 and discontinued in 1983. 1970s models and beyond were marketed under the DECsystem-10 name, especially as the TOPS-10 operating system became widely used. The PDP-10's architecture is almost identical to that of DEC's earlier PDP-6, sharing the same 36-bit word length and slightly extending the instruction set (but with improved hardware implementation). Some aspects of the instruction set are unusual, most notably the ''byte'' instructions, which operate on bit fields of any size from 1 to 36 bits inclusive, according to the general definition of a byte as ''a contiguous sequence of a fixed number of bits''. The PDP-10 was found in many university computing facilities and research labs during the 1970s, the most notable being Harvard University's Aiken Computation Laboratory, MIT's AI Lab and Project MAC, Stanford's SAIL, Computer Ce ...

Business Controls Corporation
Business Controls Corporation is a privately held computer company that developed an application-program-generator and also a series of accounting software packages. These packages were widely enough used for various business magazines to have back-of-the-book ads for companies seeking accountants with experience in one or more of them. Computer magazines ran coverage for their SB-5 application-program-generator as from time to time new versions were released, each with new or improved features. Early days The company's initial offerings were packages for the DEC PDP-8, although Business Controls Corporation also wrote custom-written programs for customers. Large customers with mainframes who also used smaller systems for departmental use and distributed processing also used BCC's services. SB-5 The addition of an application-program-generator named SB-5 that, from specifications, could generate COBOL code was a major step forward. Although this began with supporting the DEC ...

SCO Unix
Xinuos OpenServer, previously SCO UNIX and SCO Open Desktop (SCO ODT), is a closed source computer operating system developed by Santa Cruz Operation (SCO), later acquired by SCO Group, and now owned by Xinuos. Early versions of OpenServer were based on UNIX System V, while the later OpenServer 10 is based on FreeBSD 10. History SCO UNIX/SCO Open Desktop SCO UNIX was the successor to the Santa Cruz Operation's variant of Microsoft Xenix, derived from UNIX System V Release 3.2 with an infusion of Xenix device drivers and utilities. SCO UNIX System V/386 Release 3.2.0 was released in 1989, as the commercial successor to SCO Xenix. The base operating system did not include TCP/IP networking or X Window System graphics; these were available as optional extra-cost add-on packages. Shortly after the release of this bare OS, SCO shipped an integrated product under the name of SCO Open Desktop, or ODT. 1994 saw the release of SCO MPX, an add-on SMP package. At the same time, AT&T com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
