'''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]] (Semi-Automatic Business Research Environment)'', ''Deltamatic'', and ''PANAMAC''. From these ''[[ProgrammableProgrammed 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.
