A multimedia authoring system uses a graphic interface display which is implemented as a part of a flow editor and is used to create and to program interactive multimedia presentations and coursework. The authoring system also includes other editors (e.g., a database editor, an expression editor, and an object editor) used to perform other editing functions required to create presentations. The system also includes control systems (e.g., an applications mover, a videodisc controller, and a help system) which also enable the user to create, program, execute and manipulate interactive multimedia presentations. Finally, the system includes an evaluator which evaluates a programmed presentation and implements the presentation. A process of creating and evaluating a presentation using selectable icons from an icon menu area of the display screen and a grid area of the display screen includes receiving an input selecting an icon from the icon menu area, storing in the memory a data structure associated with the selected icon, displaying a new icon corresponding to the data structure on the grid area, and performing an action represented by an action identifier included in the data structure.
