PARS is an application program; TPF is an operating system. One of TPF's major optional components is a high performance, specialized database facility called TPF Database Facility (TPFDF). [4] A close cousin of TPF, the transaction monitor ALCS, was developed by IBM to integrate TPF services into the more common mainframe operating system MVS ...
ALCS is a transaction processing monitor for the IBM System/360, System/370, System/390, and IBM Z mainframes. It is a variant of TPF specially designed to provide all the benefits of TPF (very high speed, high volume, and high availability in transaction processing) but with the advantages such as easier integration into the data center ...
In addition to airlines, TPF is used by large banks, credit card companies, and hotel chains. The Hewlett Packard Enterprise NonStop system (formerly Tandem NonStop) is a hardware and software system designed for Online Transaction Processing (OLTP) introduced in 1976. [2] The system provides an extreme level of availability and data integrity.

IBM's original OS/360 sort/merge program, 360S-SM-023, program name IERRCO00 (alias SORT), supported only IBM's first-generation direct-access storage devices (DASD) [d] and tapes (2400). Support for second-generation disk drives was provided by IBM program products such as 5734-SM1 and the later 5740-SM1 ( DFSORT , alias ICEMAN, also SORT).
It was IBM Product 5734-F11. [10] CPCS is run on IBM System/360 and later IBM mainframe computers and receives the data from the document processor and can store information from the cheques, including the bank number, branch number, account number and the amount the check was written for, as well as internal transaction codes.

All modern IBM mainframe operating systems except z/TPF are descendants of those included in the "System/370 Advanced Functions" announcement – z/TPF is a descendant of ACP, the system which IBM initially developed to support high-volume airline reservations applications.
Programmed Airline Reservations System (PARS) is an IBM proprietary large scale airline reservation application, a computer reservations system, executing under the control of IBM Airline Control Program (ACP) (and later its successor, Transaction Processing Facility (TPF)). Its international version was known as IPARS. [1]
