Transaction Processing Facility

operating system (TPF) A real-time mainframe operatingsystem released by IBM around 1976. TPF is particularly

suited to organisations dealing in very high I/O message

switching and large global networks. Current users include

British Airways (reservations), VISA International

(authorisations), Holiday Inn, and Quantas.

TPF was traditionally a 370/Assembler environment although

the latest, release 4.1, contains C. Formerly known as ACP

(Airline Control Program), it was renamed "TPF" to suggests

its greater scope.

It is common for TPF sites to use IBM's MVS and VM

operating systems for off-line processing.
