XEDIT
XEDIT is a visual editor for VM (operating system), VM/CMS using block-oriented terminal, block mode IBM 3270 Computer terminal, terminals. (Line-mode terminals are also supported.) XEDIT is much more line-oriented than modern Personal computer, PC and Unix editors. For example, XEDIT supports automatic line numbers, and many of the commands operate on blocks of lines. A pair of features allows selective line and column editing. The ''ALL'' command, for example, hides all lines not matching the described pattern, and the COL (Column) command allows hiding those columns not specified. Hence changing, for example, the word NO as it appears only in columns 24 thru 28, to YES, and only on lines with the word FLEXIBLE, is doable. Another feature is a ''command line'' which allows the user to type arbitrary editor commands. Because IBM 3270 terminals do not transmit data to the computer until certain special keys are pressed [such as , a program function key (PFK), or a program acc ...

EXEC 2
EXEC 2 is an interpreted, command procedure control, computer scripting language used by the EXEC 2 Processor originally supplied with the CMS component of the IBM Virtual Machine/System Product ( VM/SP) operating system. Relation to EXEC EXEC 2 is mostly compatible with CMS EXEC but EXEC 2 scripts must begin with an &TRACE statement. Some EXEC statements and predefined variables do not exist in EXEC 2, although in some cases there are analogs. There are some minor differences in some statements and predefined functions. EXEC 2 has the following enhancements: * There is no 8-byte restriction on token length. * Statements can be up to 255 characters long. * EXEC 2 can issue commands to subcommand environments as well as CMS and CP. * EXEC 2 has additional built-in functions. * EXEC 2 has user-defined functions. * EXEC 2 commands may include subroutines and functions. * EXEC 2 has extra debugging facilities. * CMS programs can manipulate EXEC 2 variables. Some statemts of EXEC a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VM (operating System)
VM (often: VM/CMS) is a family of IBM virtual machine operating systems used on IBM mainframes System/370, System/390, zSeries, System z and compatible systems, including the Hercules (emulator), Hercules emulator for personal computers. Design The heart of the VM architecture is the ''Control Program'' or hypervisor abbreviated CP, VM-CP and sometimes, ambiguously, VM. It runs on the physical hardware, and creates the virtual machine environment. VM-CP provides full virtualization of the physical machine – including all I/O and other privileged operations. It performs the system's resource-sharing, including device management, dispatching, virtual storage management, and other traditional operating system tasks. Each VM user is provided with a separate virtual machine having its own address space, virtual devices, etc., and which is capable of running any software that could be run on a stand-alone machine. A given VM mainframe typically runs hundreds or thousands of virt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rexx
Rexx (restructured extended executor) is a high-level programming language developed at IBM by Mike Cowlishaw. Both proprietary and open-source software, open source Rexx interpreter (computing), interpreters exist for a wide range of computing platforms, and compilers exist for IBM mainframe computers. Rexx is used for scripting language, scripting, application software, application macro (computer science), macros and Software development, application development. As a general purpose scripting language, Rexx is considered a precursor to Tcl and Python (programming language), Python. Rexx is supported in a variety of environments. It is the primary scripting language in some operating systems including OS/2, MVS, VM (operating system), VM, AmigaOS and is used for macros in some software including SPF/PC, XEDIT#PC and Unix adaptations, KEDIT, The Hessling Editor, THE and ZOC (software), ZOC. With an engine installed, Rexx can be used for scripting and macros in programs that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Object REXX
Object REXX is a high-level, general-purpose, interpreted, object-oriented ( class-based) programming language. Today it is generally referred to as ooRexx (short for "Open Object Rexx"), which is the maintained and direct open-source successor to Object REXX. It is a follow-on and a significant extension of the Rexx programming language (called here "classic Rexx"), retaining all the features and syntax while adding full object-oriented programming (OOP) capabilities and other new enhancements. Following its classic Rexx influence, ooRexx is designed to be easy to learn, use, and maintain. It is essentially compliant with the "Information Technology – Programming Language REXX" ANSI X3.274-1996 standard and therefore ensures cross-platform interoperability with other compliant Rexx implementations. Therefore, classic Rexx programs typically run under ooRexx without any changes. There is also Rexx Object Oriented (“roo!”), which was originally developed by Kilowat ...

Visual Editor
A visual editor is computer software for editing ASCII, text files using a text user interface, textual or graphical user interface, graphical user interface that normally renders the content (text) in accordance with embedded markup code, e.g., HTML, Wiki#Editing, Wikitext, rather than displaying the raw text. Edits made to the page appear in wikt:real-time, real time, correctly formatted, and are often referred to as WYSIWYG (What You See Is What You Get). It is common for the software to permit switching to source-code editor mode so that the original source code can be viewed or modified. By definition, all visual editors require a refreshable display device. However, some editors using such devices, e.g., Brief (text editor), BRIEF, ISPF, gVim, KEDIT, XEDIT#THE (The Hessling Editor), THE, XEDIT, are not visual editors.

IBM 3270
The IBM 3270 is a family of Block-oriented terminal, block oriented display and printer computer terminals introduced by IBM in 1971 and normally used to communicate with IBM mainframes. The 3270 was the successor to the IBM 2260 display terminal. Due to the text color on the original models, these terminals are informally known as ''Monochrome monitor, green screen'' terminals. Unlike a character-oriented terminal, the 3270 minimizes the number of input/output, I/O interrupts required by transferring large blocks of data known as data streams, and uses a high speed proprietary communications interface, using coaxial cable. IBM no longer manufactures 3270 terminals, but the IBM 3270 protocol is still commonly used via TN3270 clients, 3270 emulator, 3270 terminal emulation or web interfaces to access mainframe-based applications, which are sometimes referred to as ''green screen applications''. Principles The 3270 series was designed to connect with mainframe computers, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COBOL
COBOL (; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL is still widely used in applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs. Many large financial institutions were developing new systems in the language as late as 2006, but most programming in COBOL today is purely to maintain existing applications. Programs are being moved to new platforms, rewritten in modern languages, or replaced with other software. COBOL was designed in 1959 by CODASYL and was partly based on the programming language FLOW-MATIC, designed by Grace Hopper. It was created as part of a U.S. Department of Defense effort to create a portable programming language for data pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syntax Highlighting
Syntax highlighting is a feature of text editors that is used for programming language, programming, scripting language, scripting, or markup language, markup languages, such as HTML. The feature displays text, especially source code, in different Text color, colours and fonts according to the category of terms. This feature facilitates writing in a structured language such as a programming language or a markup language as both structures and syntax errors are visually distinct. This feature is also employed in many programming related contexts (such as programming manuals), either in the form of colourful books or online websites to make understanding code snippets easier for readers. Highlighting does not affect the meaning of the text itself; it is intended only for human readers. Syntax highlighting is a form of secondary notation, since the highlights are not part of the text meaning, but serve to reinforce it. Some editors also integrate syntax highlighting with other featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Terminal
A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing data from, a computer or a computing system. Most early computers only had a front panel to input or display bits and had to be connected to a terminal to print or input text through a keyboard. Teleprinters were used as early-day hard-copy terminals and predated the use of a computer screen by decades. The computer would typically transmit a line of data which would be printed on paper, and accept a line of data from a keyboard over a serial or other interface. Starting in the mid-1970s with microcomputers such as the Sphere 1, Sol-20, and Apple I, display circuitry and keyboards began to be integrated into personal and workstation computer systems, with the computer handling character generation and outputting to a CRT display such as a computer monitor or, sometimes, a consumer TV, but most larger computers continued to require terminal ...

OS/2
OS/2 is a Proprietary software, proprietary computer operating system for x86 and PowerPC based personal computers. It was created and initially developed jointly by IBM and Microsoft, under the leadership of IBM software designer Ed Iacobucci, intended as a replacement for DOS. The first version was released in 1987. A feud between the two companies beginning in 1990 led to Microsoft’s leaving development solely to IBM, which continued development on its own. OS/2 Warp 4 in 1996 was the last major upgrade, after which IBM slowly halted the product as it failed to compete against Microsoft's Microsoft Windows, Windows; updated versions of OS/2 were released by IBM until 2001. The name stands for "Operating System/2", because it was introduced as part of the same generation change release as IBM's "IBM Personal System/2, Personal System/2 (PS/2)" line of second-generation PCs. OS/2 was intended as a protected mode, protected-mode successor of IBM PC DOS, PC DOS targeting t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
