HAScript, or Host Access Script, is an IBM-developed macro language with an XML syntax designed for programmatic interaction with terminal-based applications. HAScript is based on a state machine principle. The first commercial implementation appeared in IBM's Host On-Demand in the late 1990s.
IBM software products that use HAScript include WebSphere Host On-Demand (HOD), Personal Communications, and WebSphere Host Access Transformation Services (HATS). When accessing the IBM Mainframe the HAScript API allows for Host emulation whereby information from the host screen can be retrieved and reformatted within a webpage, or other software application. There has been limited adoption of HAScript as it requires an intense amount of system resources, general process overhead and Java virtual machine resources. To date, the implementation of HAScript by other software companies has been mild as the language used for communication is not universally standardized.

In computer programming, assembly language, often abbreviated asm, is any low-level programming language in which there is a very strong correspondence between the instructions in the language and the architecture's machine code instructions. Because assembly depends on the machine code instructions, every assembler has its own assembly language which is designed for exactly one specific computer architecture. Assembly language may also be called symbolic machine code.
A macro in computer science is a rule or pattern that specifies how a certain input sequence should be mapped to a replacement output sequence according to a defined procedure. The mapping process that instantiates (transforms) a macro use into a specific sequence is known as macro expansion. A facility for writing macros may be provided as part of a software application or as a part of a programming language. In the former case, macros are used to make tasks using the application less repetitive. In the latter case, they are a tool that allows a programmer to enable code reuse or even to design domain-specific languages.
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs.
In computing, a virtual machine (VM) is an emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination.
The IBM System i is an early generation of midrange computer systems for IBM i users, and was subsequently replaced by the IBM Power Systems in April 2008. The platform was first introduced as the AS/400 in June 1988 and later renamed to the eServer iSeries in 2000. As part of IBM's re-branding initiative in 2006, it was again renamed to System i. The codename of the AS/400 project was "Silver Lake", named for the lake in downtown Rochester, Minnesota, where development of the system took place.
A computing platform or digital platform is the environment in which a piece of software is executed. It may be the hardware or the operating system (OS), even a web browser and associated application programming interfaces, or other underlying software, as long as the program code is executed with it. Computing platforms have different abstraction levels, including a computer architecture, an OS, or runtime libraries. A computing platform is the stage on which computer programs can run.
Db2 is a family of data management products, including database servers, developed by IBM. They initially supported the relational model, but were extended to support object-relational features and non-relational structures like JSON and XML. The brand name was originally styled as DB/2, then DB2 until 2017 and finally changed to its present form.
IBM WebSphere refers to a brand of proprietary computer software products in the genre of enterprise software known as "application and integration middleware". These software products are used by end-users to create and integrate applications with other applications. IBM WebSphere has been available to the general market since 1998.
Jython is an implementation of the Python programming language designed to run on the Java platform. The implementation was formerly known as JPython until 1999.
Customer Information Control System (CICS) is a family of mixed language application servers that provide online transaction management and connectivity for applications on IBM mainframe systems under z/OS and z/VSE.
IBM MQ is a family of message-oriented middleware products that IBM launched in December 1993. It was originally called MQSeries, and was renamed WebSphere MQ in 2002 to join the suite of WebSphere products. In April 2014, it was renamed IBM MQ. The products that are included in the MQ family are IBM MQ, IBM MQ Advanced, IBM MQ Appliance, IBM MQ for z/OS, and IBM MQ on IBM Cloud.
WebSphere Application Server (WAS) is a software product that performs the role of a web application server. More specifically, it is a software framework and middleware that hosts Java-based web applications. It is the flagship product within IBM's WebSphere software suite. It was initially created by Donald F. Ferguson, who later became CTO of Software for Dell. The first version was launched in 1998. This project was an offshoot from IBM HTTP Server team starting with Domino Go.
Rational Application Developer for WebSphere Software (RAD) is a commercial Eclipse-based integrated development environment (IDE), made by IBM. It provides tools for visually designing, constructing, testing, analyzing, and deploying many types of applications including Java, Java EE, Web 2.0, hybrid mobile, Portal applications, and Web and REST services.
In computing, Advanced Program to Program Communication or APPC is a protocol which computer programs can use to communicate over a network. APPC is at the application layer in the OSI model, it enables communications between programs on different computers, from portables and workstations to midrange and host computers. APPC is defined as VTAM LU 6.2
IBM APP Connect Enterprise is IBM's integration broker from the WebSphere product family that allows business information to flow between disparate applications across multiple hardware and software platforms. Rules can be applied to the data flowing through the message broker to route and transform the information. The product is an Enterprise Service Bus supplying a communication channel between applications and services in a service-oriented architecture.
WebSphere sMash was a development and runtime environment from IBM for the creation of dynamic web applications using the scripting languages Apache Groovy and PHP. It contained a PHP runtime written in Java. Project Zero was the experimental software development community in which new versions of WebSphere sMash were incubated. WebSphere sMash was withdrawn from sale in 2012, with support discontinued in 2014.
Rational Software Architect is a modeling and development environment that uses the Unified Modeling Language (UML) for designing architecture for C++ and Java EE (JEE) applications and web services. Rational Software Architect is built on the Eclipse open-source software framework and includes capabilities focused on architectural code analysis, C++, and model-driven development (MDD) with the UML for creating applications and web services.
A scripting or script language is a programming language for a special run-time environment that automates the execution of tasks; the tasks could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted.
IBM Operational Decision Manager (ODM) is IBM's Business Rule Management System (BRMS). IBM ODM also incorporates IBM's implementation of Business Event Processing capabilities
The IBM WebSphere Host On-Demand Server, or HOD as it is commonly known is a Java application that runs on a Server that is deliverable via modern web servers such as the Apache web server. The application allows the end user to access IBM 3270, IBM 5250 and other Virtual terminals using the Telnet protocol whether through a secure or unsecured mode of communication. The product in its present form runs on AIX, UNIX, HP-UX, i5/OS, Z/OS, Linux, Solaris and Windows Server.
