Pathway. A Tandem product that helps simplify the development and control of online
transaction processing applications. Pathway includes SCREEN COBOL for requester
development, terminal control processes (TCPs) that use the SCREEN COBOL code to
control terminals, PATHMON for central control of all processes, and the PATHMON
command interpreter.
Pathway command file. A file containing commands that define and add the Pathway
objects required to execute an application. This file can contain all the commands
needed to start a Pathway system.
Pathway Open Environment Toolkit. See POET.
PMADL (Pathmaker Application Definition Language). A component of the Pathmaker
product that provides a conversational or batch interface to a Pathmaker catalog.
PMINSTAL. A Pathmaker utility that assists in the installation of the Pathmaker product
on a system.
PMPROJECT. A Pathmaker utility used to create and manage Pathmaker projects.
POBJCOD. A required file in the SCREEN COBOL library that contains requester object
programs.
POBJDIR. A required file in the SCREEN COBOL library that contains the directory to
the code files in POBJCOD.
POBJSYM. An optional file in the SCREEN COBOL library that contains the symbols
tables for the requester object programs.
POET (Pathway Open Environment Toolkit). A Tandem product that assists in the creation
and running of client/server applications for a Tandem system.
process. In a Tandem computer system, a process is essentially any running program.
project. 1. All the files needed to complete an application development effort using the
Pathmaker product. 2. The Pathmaker product interacting with the project files
resulting in a Pathmaker application.
project catalog. A set of files in which the Pathmaker product maintains information
about a specific ongoing project. These files reside on the project's subvolume and are
associated with only that project.
project subvolume. The subvolume in which the Pathmaker product creates a project
catalog and other project files. The project subvolume is specified when a Pathmaker
project is added using the PMPROJECT utility.
prototype. A simplified working model of an application on which a custom
application will be based. A prototype is not intended for use in production.
registered (REG) requester. A requester written outside of the Pathmaker environment
but known to a Pathmaker project. To create a Pathmaker application that accesses
such requesters, a registered requester object must be created in the Pathmaker catalog
for every outside requester directly called by the Pathmaker application. In addition,
the psuedocode for all of the outside requesters, even those not directly called, must
be placed in the SCREEN COBOL library associated with the Pathmaker application.
