{{Short description|Programming language}}
'''HAScript''', or Host Access Script, is an [[Company:IBM|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 [http://www-01.ibm.com/software/webservers/hostondemand WebSphere Host On-Demand (HOD)], [http://www.ibm.com/software/network/pcomm Personal Communications], and WebSphere [http://www.ibm.com/software/webservers/hats Host Access Transformation Services (HATS)]. When accessing the IBM Mainframe the HAScript [[API]] allows for Host [[Emulator|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.
