Abstract

A method and system for controlling the execution of an application program to effect the performing of a specialized task is provided. In preferred embodiments, an interface computer program gathers status information from the application computer program, collects user input relating to the specialized task, generates commands to send to the application program, and sends the commands to the application program to effect the execution of the specialized task. The interface computer program communicates with the application computer program preferably through the dynamic data exchange of Windows.

executing the task commands in the application computer program to effect the performing of the desired task.

2. The method of claim 1 wherein the steps of sending the status commands, receiving the status information, and sending the task commands use a dynamic data exchange.

3. The method of claim 1 wherein the application program has a predefined user interface and interface computer program provides a specialized user interface adapted to the performing of the desired task.

4. The method of claim 1 wherein the interface program and the application program execute in a windowing environment.

5. A method in a computer system for controlling execution of a computer program to effect the performing of a specialized task, the computer program having an interprocess communications interface, the computer program having commands to control the performance of tasks, the method comprising the steps of:

starting the execution of the computer program, wherein the computer program starts execution of an interface computer program; and

during execution of the interface computer program,

gathering status information from the computer program through the interprocess communications interface;

collecting user input relating to the task to be completed;

generating interprocess communications commands to effect the performance of the specialized task based on the status information and user input; and

sending the generated commands to the computer program through the interprocess communications interface to effect the controlling of the execution of the computer program.

6. The method of claim 5 wherein the interprocess communications interface is the dynamic data exchange.

7. The method of claim 5 wherein the computer program and the interface computer program execute as separate processes on the computer system.

8. A method in a computer system for controlling execution of an application computer program by an interface computer program to effect performance of a specialized task, the application computer program having commands to specify performance of tasks, the method comprising the step of:

starting execution of the application computer program;

under control of the application computer program, starting execution of the interface computer program;

under control of the interface computer program,

collecting user input relating to the specialized task to be performed;

receiving status information from the application computer program;

selecting commands to effect the performance of the specialized task by the application computer program based on the collected user input and the received status information; and

sending the selected commands to the application computer program; and

under control of the application computer program,

receiving the selected commands; and

performing tasks specified by the received commands to effect performance of the specialized task.

9. The method of claim 8 including the steps of:

under the control of the interface computer program, sending a request for status information to the application computer program; and

under control of the application computer program,

receiving the request for status information; and

sending the requested status information to the interface computer program.

10. The method of claim 8 including the steps of:

under control of the interface computer program,

receiving an indication from a user to stop execution; and

stopping execution of the interface computer program.

11. The method of claim 8, 9, or 10 wherein the computer system is a multi-processing computer system for executing computer programs as separate processes and wherein the application computer program and the interface computer program execute as separate processes.

12. A method in a computer system for providing a plurality of alternate user interfaces to an application computer program, the application computer program having a primary user interface, each alternate user interface being implemented by an interface computer program, the method comprising the steps of:

starting execution of the application computer program;

under control of the application computer program,

selecting an alternate user interface; and

starting execution of the interface computer program that implements the selected alternate user interface;

under the control of the executing interface computer program;

displaying data of the alternate user interface;

inputting a specification of a function to be performed by the application computer program;

receiving status information from the application computer program;

selecting commands of the application computer program to effect the performance of the function based on the received status information; and

sending the selected commands to the application computer program;

under control of the application computer program,

receiving the selected commands; and

executing the received commands to effect performance of the function.

13. The method of claim 12 including the steps of:

under the control of the interface computer program, sending a request for status information to the application computer program; and

sending the requested status information to the interface computer program.

14. The method of claim 12 including the steps of:

under control of the interface computer program,

receiving an indication from a user to stop execution; and

stopping execution of the interface computer program.

15. The method of claim 12, 13, or 14 wherein the computer system is a multi-tasking computer system for executing computer programs as separate tasks and wherein the application computer program and the interface computer program execute as separate tasks.

16. A method in a computer system for performing a task by an application program, the application program having a plurality of low-level commands, each low-level command for performing a portion of the task, the method including the steps of:
