Abstract
Abstract A computer system comprises a memory for storing communication history information between a terminal and an execution program, and an output message file for storing sets of communication history conditions and output messages corresponding to those conditions. When the terminal issues a message output request, only the output message that meets the communication history condition is selected from the output message file and outputted to the terminal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
138 words
A computer system for outputting a message for operation guidance to a plurality of terminals, comprising: communication history logging means connected to a communication line extending between said terminals and an execution program for logging histories of communication information between each of the terminals and said execution program; an output message file for storing a plurality of sets of communication history conditions and output messages corresponding thereto; and message selection means, connected to said communication logging means and said output message file and responsive to the issuing of a message output request from a terminal, for selecting only the output message that meets the communication history condition from said output message file in accordance with the content of said communication history logging means and for outputting the selecting output message to said terminal issuing said message output request.
Claim 2
Dependent Claim
138 words
A computer system for outputting a message for operation guidance to a plurality of terminals, comprising: communication history logging means connected to a communication line extending between said terminals and an execution program for logging histories of communication information between each of the terminals and said execution program; an output message file for storing a plurality of sets of communication history conditions and output messages corresponding thereto; and message selection means, connected to said communication logging means and said output message file and responsive to the issuing of a message output request from a terminal, for selecting only the output message that meets the communication history condition from said output message file in accordance with the content of said communication history logging means and for outputting the selecting output message to said terminal issuing said message output request.
