Abstract
The processing of computer program delays and timers is placed outside the computer mainframe in a routine timer in order to reduce the amount of computer processing capability dedicated to keeping track of time intervals to be performed by the computer. Such a routine is particularly applicable to systems controlling a plurality of devices in which each device is controlled by a separate computer program designed to operate the device in a predetermined manner in response to specific conditions detected at the hardware site and transmitted to the computer.
