Text Processing Utility
The DEC Text Processing Utility (or DECTPU) is a dedicated programming language developed by Digital Equipment Corporation (DEC) to easily create multi-functional text editors. TPU is part of OpenVMS. It can be used on a terminal, a console, or on a graphical system like DECwindows. Functionality TPU provides text buffer management APIs in concert with window management APIs which are targeted for the VT-XXX line of terminals. This allowed split-screen windows with scrolling and hence multiple views of the same buffer content. There are also key mapping APIs provided, allowing a wide range of functionality for editing text. The keyboard mapping could be easily adapted by the admin or the user. Users could write their own specific editor, to e.g. translate text or short (error) messages to multiple natural languages in a synchronised small text window. The text editor is callable, so you could have small text editors built into specific applications, e.g. a simple mail client. ...

Digital Equipment Corporation
Digital Equipment Corporation (DEC ), 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 forced to resign in 1992, after the company had gone into precipitous decline. The company produced many different product lines over its history. It is best known for the work in the minicomputer market starting in the mid-1960s. The company produced a series of machines known as the PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space. As microcomputers improved in the late 1980s, especially wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Text Editor
A text editor is a type of computer program that edits plain text. Such programs are sometimes known as "notepad" software (e.g. Windows Notepad). Text editors are provided with operating systems and software development packages, and can be used to change files such as configuration files, documentation files and programming language source code. Plain text and rich text There are important differences between plain text (created and edited by text editors) and rich text (such as that created by word processors or desktop publishing software). Plain text exclusively consists of character representation. Each character is represented by a fixed-length sequence of one, two, or four bytes, or as a variable-length sequence of one to four bytes, in accordance to specific character encoding conventions, such as ASCII, ISO/IEC 2022, Shift JIS, UTF-8, or UTF-16. These conventions define many printable characters, but also non-printing characters that control the flow of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Inter-process Communication
In computer science, inter-process communication or interprocess communication (IPC) refers specifically to the mechanisms an operating system provides to allow the processes to manage shared data. Typically, applications can use IPC, categorized as clients and servers, where the client requests data and the server responds to client requests. Many applications are both clients and servers, as commonly seen in distributed computing. IPC is very important to the design process for microkernels and nanokernels, which reduce the number of functionalities provided by the kernel. Those functionalities are then obtained by communicating with servers via IPC, leading to a large increase in communication when compared to a regular monolithic kernel. IPC interfaces generally encompass variable analytic framework structures. These processes ensure compatibility between the multi-vector protocols upon which IPC models rely. An IPC mechanism is either synchronous or asynchronous. Synchr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EVE (text Editor)
EVE (introduced as the Extensible VAX Editor, later as the ''Extensible'' Versatile ''Editor'') is a flexible text editor that is part of the VMS operating system. EVE is implemented by using the Text Processing Utility (TPU). The Emacs editor features an EVE emulation (as an add-on). Editor control EVE is invoked via: $ EDIT/TPU ''filename'' Since the EVE editor was designed for use from a VT100 or VT220 terminal, many keyboard conventions introduced for personal computers do not work. ; recall the EVE command line (with previous command); use Ctrl-U to clear it , - , style="font-weight: bold; text-indent: 3em;" colspan="2" , Text deleting , - , Backspace , , erases the character to the left of the cursor , - , Ctrl-U , , erase start of line; deletes everything to the left of the cursor to the start of the line , - , Ctrl-X , , erase start of line; deletes everything to the left of the cursor to the start of the line , - , Ctrl-J , , erase word; deletes the word unde ...

EDT (Digital)
EDT is a character-based text editor from Digital Equipment Corporation (DEC) running on PDP-11 (RSX-11, RSTS/E and RT-11), and later for its OpenVMS operating system. It can respond to single keystrokes, and uses function keys to implement commands to the editor. EDT was introduced originally as a line-mode editor. The screen mode was developed first as the Keyboard Editor (KED) on RT-11 as part of the FMS-11 project by Darrell Duffy; EDT on the other operating systems was then enhanced to be compatible with KED. The editor contains both line mode commands and a screen based editor. In screen mode, the default action for the user is to directly update text as they type, with special commands available by pressing keypad commands. Arrow keys allow for simple navigation, while keypad commands allow for more complex navigation and searches. As with many user interfaces developed around this time, EDT uses the " Gold Key" style of input first developed for the WPS-8 word processing ...
