Abstract: The process of the present invention is an emulation process for automatically making changes and/or revisions to computer data files from a database of file records stored in a computer. The process includes the steps of identifying the events that occur while accomplishing a given task, recording in memory the operation of a human operator interacting with a graphical user interface of a computer to form one or more emulated responses to each event representing event handlers for performing the task, forming a collection of events for such task and a collection of the recorded emulated event handlers corresponding to each event for such task, selecting a batch of file records that require changes and/or revisions from the database of file records, loading a specified task and the recorded collection of events and emulated event handlers for such task into a computer; and executing the task on each selected file record by matching each emulated event handler in memory to a given event.
