COMPUTER MONITORED OR CONTROLLED SYSTEM WHICH MAY BE MODIFIED AND DE-BUGGED ON-LINE BY ONE NOT SKILLED IN COMPUTER PROGRAMMING

A computer monitored or controlled system is equipped with an interactive debugging system which enables a systems engineer to modify the system configuration in a simple manner. At any time, the systems engineer may obtain from the system a complete, understandable description of the system's present operating configuration. He may then modify any part of the system. Operation of portions of the system may be simulated, and detailed records of system and simulation operations may be automatically obtained.
