Abstract

A user inquiry facility and method are described for use in a computerized data processing system which provides for monitoring of conversations or information transmission between a user of the data processing system, during the execution of the user'"'"'s program, and a communication partner (which could include a database or other facility) associated with the data processing system. Task progress tracing information is selected from the conversations and stored. The stored information is updated to keep it current with the progress of the task of the user'"'"'s program. An instruction is provided by the facility or method which, when activated, by the user selects task progress tracing information from the stored information and after formatting it for readability is transmitted to the user-s display or terminal. The inquiry facility is independent of the successful operation of the user'"'"'s program so that it can feedback information to the user about any failure in the program or in any communication paths used for the conversations.

7. The multiuser data processing system of claim 2 further comprising an operating system for said data processing system with an application requestor facility program interfacing between said user program and said communication partner for the transmission of information therebetween wherein

said transmission means is under the control of said operating system and independent of said user program.

8. The multiuser data processing system of claim 5 further comprising an operating system for said data processing system with an application requestor facility program interfacing between said user program and said communication partner for the transmission of information therebetween wherein

said transmission means is under the control of said operating system and independent of said user program and said application requestor.

9. The multiuser data processing system of claim 8 wherein said application requestor is associated with a single user.

10. The multiuser data processing system of claim 8 wherein said application requestor is associated with a plurality of users.

11. The multiuser data processing system of claim 2 wherein said system further comprises:

an operating system for controlling the operation of said data processing system.

12. The multiuser data processing system of claim 11 wherein

said inquiry means comprises means for activating a priority command as part of said operating system which results in the suspension of any user program operation, selection of task progress status information from said storage means, and transmission to said user'"'"'s display.

13. The multiuser data processing system of claim 12 wherein said user'"'"'s display includes any of the following:

a printer;

a viewing screen;

or

a storage file accessible by the user for display purposes.

14. The multiuser data processing system of claim 12 wherein said storage means comprises means for selecting storage locations controlled by said operating system within said application requestor.

15. The multiuser data processing system of claim 2 wherein said selection means comprises means for selecting the following task progress information from the information transmitted between said user and said communication partner:

identification of the user, identification of the communication partner, user program status, communication wait information, time of collection of the information from said storage.

16. The multiuser data processing system of claim 2 wherein said inquiry facility comprises means for implementing a separate instruction path from the user to said storage means, unaffected by the progress of the user program, to activate said inquiry means.

17. The multiuser data processing system of claim 2 wherein said inquiry facility comprises means for implementing a separate instruction path parallel to an information communication path used in the execution of the user program.

20. The multiuser data processing system of claim 2 wherein said communication partner comprises a remote data processing or database system linked to the data processing system of said user.

21. The multiuser data processing system of claim 7 wherein said application requestor includes:
