General Considerations

An application may be placed at any CPU within the network. Consequently, application programs are portable to the extent they can operate in any CPU that is under control of an operating system in which the application was designed to be executed. These application programs need only to interface to the network facilities supported by the TPF System. Thus, a CPU which does not contain the TPF System must contain an interface program which adheres to the cross domain protocols supported by the TPF System. The Routing Control Parameter List (RCPL) when used as a message header, in essence, defines the TPF message routing protocol.

The term System Control Program (SCP) is loosely used throughout this document to indicate a control program other than the TPF system .
