|(application)||Programmable Airline Reservation System - (PARS) An IBM proprietary large scale airline
reservation application, executing under the control of IBM's
ACP (and later its successor, TPF).|
In the early days of automated reservations systems in the 1960s and 1970s the combination of ACP and PARS provided unprecendented scale and performance from an on-line real-time system, and for a considerable period ranked among the largest networks and systems of the era.
IPARS was the international version.
