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 ...

ARexx
ARexx is a Rexx interpreter for Amiga, written in 1987 by William S. Hawes, with a number of Amiga-specific features beyond standard Rexx. An ARexx script can communicate with software that implements an ''ARexx port''. An Amiga application can define a set of commands and functions for ARexx to address, thus making the capabilities of the software available to an ARexx script. Several applications support running an ARexx script as a macro. An ARexx script can execute commands and functions in multiple applications which allows a script to integrate the functionality of the applications. For example, an ARexx script could extract data from a database, insert the data into a spreadsheet to perform calculations on the data, then insert tables and charts based on the results into a word processor document. ARexx allows a script to communicate with applications that are "ARexx compatible" able to receive commands from ARexx and execute them. Notable examples include: the ''Mi ...

NetRexx
NetRexx is an open source, originally IBM's, variant of the REXX programming language to run on the Java virtual machine. It supports a classic REXX syntax, with no reserved keywords, along with considerable additions to support object-oriented programming in a manner compatible with Java's object model, yet can be used as both a compiled and an interpreted language, with an option of using only data types native to the JVM or the NetRexx runtime package. The latter offers the standard Rexx data type that combines string processing with unlimited precision decimal arithmetic. Integration with the JVM platform is tight, and all existing Java class libraries can be used unchanged and without special setup; at the same time, a Java programmer can opt to just use the Rexx class from the runtime package for improved string handling in Java syntax source programs. NetRexx is free to download from the Rexx Language Association. IBM announced the transfer of NetRexx 3.00 source code to t ...

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 ...

Scripting Language
In computing, a script is a relatively short and simple set of instructions that typically automation, automate an otherwise manual process. The act of writing a script is called scripting. A scripting language or script language is a programming language that is used for scripting. Originally, scripting was limited to automating an operating system shell and languages were relatively simple. Today, scripting is more pervasive and some languages include modern features that allow them to be used for Application software, application development as well as scripting. Overview A scripting language can be a general purpose language or a domain-specific language for a particular environment. When embedded in an application, it may be called an extension language. A scripting language is sometimes referred to as very high-level programming language if it operates at a high level of abstraction, or as a control language, particularly for job control languages on mainframes. The te ...

AmigaOS
AmigaOS is a family of proprietary native operating systems of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola Motorola 68000 family, 68000 series of 16-bit and 32-bit microprocessors. Later versions, after Commodore's demise, were developed by Haage & Partner (AmigaOS 3.5 and 3.9) and then Hyperion Entertainment (AmigaOS 4.0-4.1). A PowerPC microprocessor is required for the most recent AmigaOS 4-release. AmigaOS is a single-user operating system based on a preemptive multitasking kernel (operating system), kernel, called Exec (Amiga), Exec. It includes an abstraction of the Amiga's hardware, a disk operating system called ''AmigaDOS'', a windowing system Application programming interface, API called Intuition (Amiga), ''Intuition'', and a desktop environment and file manager called Workbench (AmigaOS), ''Workbenc ...

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 ...

Macro (computer Science)
In computer programming, a macro (short for "macro instruction"; ) is a rule or pattern that specifies how a certain input should be mapped to a replacement output. Applying a macro to an input is known as macro expansion. The input and output may be a sequence of lexical tokens or characters, or a syntax tree. Character macros are supported in software applications to make it easy to invoke common command sequences. Token and tree macros are supported in some programming languages to enable code reuse or to extend the language, sometimes for domain-specific languages. Macros are used to make a sequence of computing instructions available to the programmer as a single program statement, making the programming task less tedious and less error-prone. Thus, they are called "macros" because a "big" block of code can be expanded from a "small" sequence of characters. Macros often allow positional or keyword parameters that dictate what the conditional assembler program gen ...

PL/I
PL/I (Programming Language One, pronounced and sometimes written PL/1) is a procedural, imperative computer programming language initially developed by IBM. It is designed for scientific, engineering, business and system programming. It has been in continuous use by academic, commercial and industrial organizations since it was introduced in the 1960s. A PL/I American National Standards Institute (ANSI) technical standard, X3.53-1976, was published in 1976. PL/I's main domains are data processing, numerical computation, scientific computing, and system programming. It supports recursion, structured programming, linked data structure handling, fixed-point, floating-point, complex, character string handling, and bit string handling. The language syntax is English-like and suited for describing complex data formats with a wide set of functions available to verify and manipulate them. Early history In the 1950s and early 1960s, business and scientific users programmed fo ...
