Abstract: A data processor/controller contains a program representative of a logic configuration required to control the sequencing of operations in equipment external thereto. The processor/controller includes means for accumulating the results of a plurality of logic operations as specified by the program and providing a final result representative of conditions in the logic configuration. The final result has a condition which is used to control the external equipment.
