Transaction Processing Facility (TPF) [2] is an IBM real-time operating system for mainframe computers descended from the IBM System/360 family, including zSeries and System z9. TPF delivers fast, high-volume, high-throughput transaction processing, handling large, continuous loads of essentially simple transactions across large, geographically ...
SabreTalk is a discontinued dialect of PL/I for the S/360 IBM mainframes running the TPF platform. SabreTalk was developed jointly by American Airlines, Eastern Air Lines and IBM. SabreTalk is known as PL/TPF (Programming Language for TPF). [1] In 1973, Eastern Air Lines' computing division was selling the SabreTalk compiler for US$95,000. [2]
Whereas TPF runs as a stand-alone OS, ALCS is designed to run as an application on top of MVS/OS/390/z/OS. However, the API it provides to applications is very similar to that on TPF , so applications written for TPF can run on ALCS with minimal modifications: typically fewer modifications than are required to move from one release of TPF to ...
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.
IBM Z Development and Test Environment can be used for education, demonstration, and development and test of applications that include mainframe components. The Z390 and zCOBOL is a portable macro assembler and COBOL compiler, linker, and emulator toolkit providing a way to develop, test, and deploy mainframe compatible assembler and COBOL ...
The high performance PARS operating system evolved from ACP (Airlines Control Program) to TPF (Transaction Processing Facility). [ 1 ] In the early days of automated reservations systems in the 1960s and 1970s the combination of ACP and PARS provided unprecedented scale and performance from an on-line real-time system, and for a considerable ...
A mainframe computer, informally called a mainframe or big iron, [1] is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.
A copy of the mainframe version of AIX or Linux. In the mainframe environment, these operating systems often run under VM, and are handled like other guest operating systems. (They can also run as 'native' operating systems on the bare hardware.) There was also the short-lived IX/370, as well as S/370 and S/390 versions of AIX (AIX/370 and AIX ...
