Abstract

A method of simultaneously executing one or more computer application programs in one or more host computer system under the control of a second computer system, where the second computer system performs operations on data and instructions and the host computer systems generates presentation information based on the application programs, involves establishing selected parameters in the host computer presentation information, interpreting selected portions of the host computer system'"'"'s presentation information, providing the interpreted selected portions of the host computer system'"'"'s presentation information as input to a computer program resident in the second computer system, examining the host computer system presentation information at the second computer system to detect the presence therein of one or more the selected parameters, continuing operation of the second computer system during the examining for the selected parameters, and generating an indication to the second computer system of the detection of one or more of the selected parameters in the host computer system presentation information.

Claims

1. A method of simultaneously executing one or more computer application programs in one or more host computer systems under the control of a plurality of secondary computer systems where said computer application programs may be dissimilar to each other, and said host computer systems may be dissimilar to each other, said host computer systems generating presentation information based on said application programs, said method comprising the steps of:

establishing a plurality of relevant selected parameters in said host computer presentation information;

said relevant selected parameters having a variable time of occurrence and context in said presentation information;

interpreting selected portions of said host computer system'"'"'s presentation information in said application programs being executed;

providing said interpreted selected portions of said host computer system'"'"'s presentation information as input to one computer program resident in a selected one of said plurality of secondary computer systems;

examining said host information at said selected one of said secondary computer systems to detect the presence therein of one or more of said selected parameters;

said examination of said host computer system presentation information being dependent on the time of occurrence and the context of said selected parameters in said host computer presentation information;

continuing said operation of said selected one of said secondary computer systems and of the other of said secondary computer systems during examining for said selected parameters; and

generating an indication to said selected one of said secondary computer systems of the detection of one or more of said relevant selected parameters in said host computer system presentation information.
