<p>A method is disclosed which informs a user of a data processing system about which of his previous selections in a current data processing session have disabled, or otherwise "affected", selections which would ordinarily be selectable. The method is practiced in a data processing system which includes a central processing unit (CPU), a random access memory (RAM), a means of inputting user selections such as a keyboard and a mouse and a means of displaying the results of such selections to the user. A plurality of program modules and data objects are resident in the memory. Control of the data processing system is mainframed by listing the selections available to the user on series of menus presented on the display means. The CPU instructs the display means to display the menu which corresponds to that particular point in the program. Following the method of the present invention, the CPU has kept track of the selections made by the user. By referring to a special data file which correlates these past selections to the list of actions displayed in the current menu, the CPU determines which of these actions are "affected". These affected actions are then denoted on the menu in some way, e.g., changing the affected action's color, marking the affected actions with a special symbol, etc. Responsive to the user placing the input focus on an affected action, the CPU presents a list of the past selections which cause the action to be affected on the display means. One preferred embodiment of the invention would allow a user to deselect the past selections which cause the action to be affected, and thereby transform the affected action to an unaffected action. The user could then perform the desired action with the remaining past selections. <IMAGE></p> |
