API. See application program interface (API).
application program. One of the following: A software program written for or by a user for a
specific purpose. A computer program that performs a data processing function rather

XML element. An attribute has a name and a value.
client. A software process, hardware device, or combination of the two that requests
services from a server. Often, the client is a process residing on a programmable

exception. An event during program execution that prevents the program from continuing
normally; generally, an error. Java methods raise exceptions using the throw keyword
and handle exceptions using try, catch, and finally blocks.
Guardian. An environment available for interactive or programmatic use with the operating
system. Processes that run in the Guardian environment usually use the Guardian
system procedure calls as their application program interface; interactive users of the
Guardian environment usually use the HP Tandem Advanced Command Language
(TACL) or another HP product’s command interpreter. Contrast with Open System
Services (OSS).
HP NonStop™ operating system. The operating system for HP NonStop systems.
HP Tandem Advanced Command Language (TACL). The user interface to the operating
system. The TACL product is both a command interpreter and a command language.
Users can write TACL programs that perform complex tasks or provide a consistent
user interface across independently programmed applications.
