TS/MP Pathsend and Server Programming Manual (H06.05+, J06.03+)

About This Manual
This manual describes how to write two types of programs as part of a Pathway application:
requester programs that use the Pathsend application program interface (API) and server programs
that service requests from all types of Pathway requesters.
This section describes the purpose and the contents of this manual and of other manuals closely
related to this manual.
This manual is one of a set of manuals that describe the TS/MP and the HP NonStop Pathway/iTS
products. The contents of these products are:
• TS/MP: This product consists of the PATHMON process, the LINKMON process or the ACS
subsystem processes, the PATHCOM process and interface, and the Pathsend procedure calls.
• Pathway/iTS: This product consists of the terminal control process (TCP), the SCREEN COBOL
compiler and run-time environment, and the SCREEN COBOL Utility Program (SCUP).
Together with the HP NonStop Transaction Management Facility (TMF) product, the TS/MP product
forms the foundation for the open transaction processing and client/server products on HP
NonStop™ systems. Such products include the NonStop Tuxedo system, the RSC/MP product, and
the Pathway Open Environment Toolkit (POET).
The Pathway/iTS product supports requester programs that run in the Guardian environment and
communicate with terminals and intelligent devices. It requires the services of the TS/MP product.
Purpose of This Manual
This manual is a combined reference manual and programming guide. It contains reference
information about the Pathsend procedure calls, and it also contains information about how to
design and code applications using these calls.
In addition, this manual contains information about how to design and code Pathway servers to
be used with all types of requesters and clients.

Who Should Read This Manual
This manual is intended for programmers writing Pathway applications that include Pathsend
requesters, Pathway servers, or both. Readers should be experienced programmers familiar with
the Guardian environment and the HP programming languages they are using.
What Is in This Manual
This manual contains application design and programming information for writers of Pathsend
requesters and Pathway servers. This information includes syntax, usage, and error-handling
information for the Pathsend procedure calls. The manual has this structure:
