Abstract: A new decision table and method of using the decision table with data processing apparatus are disclosed. A general purpose driver is provided for executing various decision tables. When a problem program reaches the point where a decision table is to be executed, the problem program calls the driver and identifies the selected decision table. The condition stub of the decision table includes a series of instructions from which the driver forms a condition mask. The driver selects the appropriate action according to the condition mask and a set of rules and an action stub in the decision table. The action may comprise a single instruction or series of related instructions or several independent instruction or groups of instructions.
