Abstract

Abstract A method of, and apparatus for, running several applications (50) concurrently on a processing system. Virtual terminals (30) are created for running the applications. However, the virtual terminals perform as though the processing system were a single terminal system. In this way, any application written for a single terminal system can run in this multiple virtual terminal environment. For interaction with one of the several applications running on this system, the real physical resources of the system are reallocated to the virtual terminal running the selected application.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 41 words
A method of providing for the concurrent running of a plurality of applications (50) written for a particular system, characterized by creating a plurality of virtual terminals (30) each of which performs as though the system were a single terminal system.
Claim 2
Independent Claim 41 words
A method of providing for the concurrent running of a plurality of applications (50) written for a particular system, characterized by creating a plurality of virtual terminals (30) each of which performs as though the system were a single terminal system.
Claim 3
Dependent Claim 28 words
A method as claimed in claim 1, characterized by adding structure (30,50) to said particular system for creating a plurality of virtual terminals (30) for running said applications.
Claim 4
Dependent Claim 29 words
A method as claimed in claim 1, characterized by reallocating real physical resources of a system running said plurality of applications to one of said plurality of virtual terminals.
Claim 5
Independent Claim 61 words
A system for concurrently running a plurality of applications (50), said system comprising: a) means (340,350) for creating a plurality of virtual terminals; and b) means (310,320) for causing each of said terminals to operate in said system as though said system were a single terminal system, whereby applications written for a single terminal system can be run on said terminals.
Claim 6
Independent Claim 61 words
A system for concurrently running a plurality of applications (50), said system comprising: a) means (340,350) for creating a plurality of virtual terminals; and b) means (310,320) for causing each of said terminals to operate in said system as though said system were a single terminal system, whereby applications written for a single terminal system can be run on said terminals.
Claim 7
Dependent Claim 26 words
A system as claimed in claim 4 characterized by means for reallocating real physical resources of said system to one of said plurality of virtual terminals.
