Pathmaker Programming Guide

About This Manual
xx 067868 Tandem Computers Incorporated
Application developers who are creating services and servers for a Pathmaker
application must already know how to code in COBOL85 or C, and NonStop SQL, if
applicable. They must also know how to test and debug a Pathway server. If
additional code is to be incorporated into a Pathmaker requester, application
developers must know how to write and debug SCREEN COBOL code.
Individuals who are responsible for setting up a Pathmaker project, managing the
development effort, or installing the application for testing or production must have a
thorough knowledge of Pathway and the Data Definition Language (DDL) in addition
to the prerequisite skills listed for application developers.

Section 1, “Pathmaker Tasks,” presents an overview of the major tasks performed
during a Pathmaker application development effort. This section is especially helpful
to anyone using the Pathmaker product for the first time. The details required to
complete the tasks outlined here are provided in the remainder of this manual and in
the Pathmaker Reference Manual.
Section 2, “Preparing for Pathmaker Application Development,” describes the tasks
that should be completed and itemizes the issues that need to be addressed while
planning and setting up a Pathmaker application development effort. Details about
the activities performed to prepare for a Pathmaker application development effort
such as designing a Pathmaker application, naming Pathmaker objects, and creating
shared code are presented. The portions of the Pathmaker product used for each of
these activities are identified. This information is of interest to individuals who are
responsible for organizing a development effort or designing a Pathmaker application.
