{{Short description|Operating system developed by IBM beginning about 1965}}

'''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.

{{History of IBM mainframe operating systems|tpf}}

'''IBM Airline Control Program''', or '''ACP''', wasis thea discontinued [[operating system]] developed by [[IBM]] beginning about [[1965]]. In contrast to previous [[airline]] [[transaction processing systemssystem]]s, 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 havehad a different, machine-specific transaction system.

==Overview==

Development began with ''[[Sabre (travel reservation system)|SABRE]] (Semi-Automatic Business Environment Research Environment)'', ''Deltamatic'', and ''PANAMAC''. From these, the ''PARS ([[Programmed Airline ReservationReservations System]] (PARS)'' was developed. In 19681969 the control program, ''ACP'', was separated from PARS;. PARS keepingkept the functions for processing [[airline]] reservations and related data.

In FebruaryDecember [[1979]], ACP became known as ACP/TPF and then just [[Transaction Processing Facility|TPF]] (Transaction Processing Facility).<ref>{{cite as the transaction operating system became more widely implemented by businesses other than the major airlines.web

}}</ref> 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.

The last "free" release of ACP, 9.2.1, was intended for use in bank card and similar applications. It was shipped on a "[[Magnetic_tape_data_storage#IBM_formats|mini-reel]]" which contained a complete ACP system and its libraries for restoration to [[IBM 3340]] disk drives. From that complete system one could easily create derivative works. A [[hypervisor]] was included, which allowed OS/370 [[OS/VS1|VS1]] or VS2 ([[IBM Single Virtual Storage (SVS)|SVS]] or [[MVS]]) to be run as a "guest" OS under ACP itself. The end-user documentation, which was shipped with the tape, took almost 60 linear inches of shelf space.

Current IBM articles<ref>[http://www-306.ibm.com/software/htp/tpf/pages/products.htm IBM TPF Family of Products]</ref> reference the ''IBM Airline Control System (ALCS)'' and, for some cases, distinguish between ALCS and TPF.

See also [[ALCS transaction monitor|''IBM Airline Control System (ALCS)'']], a variant of TPF specially designed to provide all the benefits of TPF (very high speed, high volume, high availability transaction processing) but with the advantages such as easier integration into the data center offered by running on a standard IBM operating system platform.
