'''IBM Airline Control Program''', or '''ACP''', was the [[operating system]] developed by [[IBM]] beginning about [[1965]]. In contrast to previous airline transaction processing systems, the most notable aspect of ACP is that it was designed to run on most models of the [[IBM]] [[System/360]] mainframe computer family. This departed from the earlier model in which each airline would have a different, machine-specific transaction system.

Development began with ''[[Sabre_(computer_system)|SABRE]] (Semi-Automatic Business Research Environment)'', ''Deltamatic'', and ''PANAMAC''. From these ''[[Programmed Airline Reservation System]] (PARS)'' was developed. In 1968 the control program, ''ACP'' was separated from PARS; PARS keeping the functions for processing [[airline]] reservations and related data.

In February [[1979]], ACP became known as ACP/TPF and then just [[Transaction Processing Facility|TPF]] (Transaction Processing Facility) as the transaction operating system became more widely implemented by businesses other than the major airlines, such as online credit card processing, hotel and rental car reservations, police emergency response systems, and package delivery systems.
