CP6100 I/O Process Programming Manual

SECTION 2
USING CP6100: PROGRAMMING
This section is for programmers who plan to use CP6100. It
describes:
• the interface between your application and a communication
line
• the services CP6100 provides to your application
• background information useful for handling errors and
exceptions
Other books describe the available protocol modules. See
the preface for a list of those books. (Some protocols may
be added after the publication of this manual.)
WRITING APPLICATIONS THAT USE CP6100
For an application to communicate with terminals or mainframes on
CP6100 lines, several pieces of software are needed:
• An application that you write. This application consists of
processes that perform business functions and possibly some
protocol functions. Section 1 mentioned the tradeoffs between
writing one process for both sorts of functions and writing
separate processes for different sorts of functions.
In the rest of this book, "application" refers to the program
you write to do protocol functions. The same program may be
part of many different business applications.
