Apparatus and method for emulating terminal attributes using a web server

摘要

A method, computer program product and apparatus for controlling an attribute of a data element used by an input/output device of which a display space is controlled by a markup language. The method comprises steps of: defining a unique identifier; associating the unique identifier with a statically-defined attribute; providing the unique identifier to allow an application program to create a runtime definition of the attribute in memory; checking for the existence of the runtime definition in the memory; and if the runtime definition is in the memory, refraining from acting upon the statically-defined attribute associated with the unique identifier in favor of acting upon the runtime definition. This permits a terminal template-based application to dynamically control attributes in a page defined with a markup language such as HTML.
