A graphical method for sequencing computer control task uses objects to represent
the task to be performed by the computer. The objects are placed in a directional
field having a directional attribute which specifies how the tasks are to be sequenced.
The sequence of tasks to be performed collectively defines a procedure. When the
procedure is initiated, the computer automatically sequences the task within the
procedure based on the relative special location of the task objects and the directional
attribute. The sequence can be modified by changing the relative location of the
task objects or by changing the directional attribute.
