Abstract
Abstract Apparatus and method whereby a first digital computer system (231) may be controlled by a second digital computer system (233). The two digital computer systems are connected by data transfer apparatus (213, 210). A program - (227) in the second digital computer system constructs a call protocol (215) specifying a routine to be called in the first digital computer system. The data transfer apparatus transfers the call protocol to the first digital computer system, and a program (211) in the first digital computer system performs the call. Also disclosed are a return protocol (217) which may be employed to return data from the called routine to the second computer system, call protocols containing arguments, the use of call and return protocols to call system and user routines, and preferred forms of the call and return protocols.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
96 words
Apparatus for control of a first computer (231) system responsive to callable programs (205) by a second computer system (233) connected by message transport means (210, 213) to the first computer system, characterized by 1 . message providing means (227) in the second computer system for providing a call message (215) specifying a callable program in the first computer system to the message transport means, and 2. message interpretation means (211) in the frist computer system for receiving the call message from the message transport means and calling the callable program specified in the call message.
Claim 2
Dependent Claim
96 words
Apparatus for control of a first computer (231) system responsive to callable programs (205) by a second computer system (233) connected by message transport means (210, 213) to the first computer system, characterized by 1 . message providing means (227) in the second computer system for providing a call message (215) specifying a callable program in the first computer system to the message transport means, and 2. message interpretation means (211) in the frist computer system for receiving the call message from the message transport means and calling the callable program specified in the call message.
Claim 3
Dependent Claim
44 words
Control apparatus of claim 1 characterized in that the call message (215) further contains call data (239) for use in calling the specified callable program (205), and the message interpretation means (211) uses the call data - (239) in calling the specified callable program.
Claim 4
Dependent Claim
62 words
Control apparatus of claim 1 or 2, characterized in that the message interpretation means (211) in the first computer system (231) provides a return message (217) containing the result of the call of the callable program to the message transport means, and the message providing means (217) in the second computer system (233) receives the return message from the message transport means.
Claim 5
Dependent Claim
43 words
Control apparatus of claim 3, characterized in that the message providing means (227) in the second computer system (233) is a processor means (221) executing a callable program (205); and the processor means executes a return operation after receiving the return message (217).
Claim 6
Dependent Claim
19 words
Control apparatus of claim 3 or 4, characterized in that the return message (217) further contains return data (243).
Claim 7
Dependent Claim
47 words
Control apparatus of claim 5, characterized in that the message providing means (227) in the second computer system (233) is a processor means (221) executing a callable program (205), and the processor means provides the return data (243) to the calling program and executes a return operation.
Claim 8
Dependent Claim
19 words
Control apparatus of any of claims 1 to 6, characterized in that the callable programs (205) include system programs.
Claim 9
Dependent Claim
112 words
Control apparatus of claim 1, characterized in that the callable programs (205) are subdivided into a plurality of sets of callable programs; the message interpretation means (211) is subdivided into message receiving means (751) and a plurality of server means (771, 773) corresponding to the plurality of sets of callable programs; the message providing means (227) further provides a server specifier message (607) specifiying one of the server means prior to the call message; the message receiving means (751) responds to the server specifier message by slecting one of the server means - (771, 773); and the selected server means responds to the call message by calling the specified callable program (205).
Claim 10
Dependent Claim
31 words
Control apparatus of claim 8, characterized in that the server means include system server means (773) for calling specified system programs and user server means (771) for calling specified user programs.
Claim 11
Dependent Claim
43 words
Apparatus for mutual control of a first computer system (301) responsive to first callable programs (311) and a second computer system (303) responsive to second callable programs (337), the first and second computer systems being connected by message transfer means (325), characterized by
Claim 12
Dependent Claim
43 words
Apparatus for mutual control of a first computer system (301) responsive to first callable programs (311) and a second computer system (303) responsive to second callable programs (337), the first and second computer systems being connected by message transfer means (325), characterized by
