LU 6.2 API Application Programmer's Reference Guide (30294-90008)

Organization
This manual is divided into the following sections and appendices:
Chapter 1, The SNA Network and LU 6.2 API, gives an overview of the
SNA environment and Advanced Program-to-Program Communication.
It explains the LU 6.2 architecture and Hewlett-Packard’s
implementation of LU 6.2 API.
Chapter 2, Conversations, describes what a conversation is and the
different kinds of conversations that application programs can have. It
explains the tasks necessary to establish a conversation.
Chapter 3, Intrinsic Overview, discusses how LU 6.2 API intrinsics are
used to implement the conversations described in chapter 2.
Chapter 4, Conversation States, gives an explanation of conversation
states and explains the relationship between states and conversations.
Chapter 5, Intrinsic Descriptions, describes each of the intrinsics
available with LU 6.2 API.
Chapter 6, Buffer Management, explains how LU 6.2 API manages its
send and receive buffers and the impact this has on LU 6.2 API
applications.
Chapter 7, Debugging, explains the user trace and the steps for
debugging LU 6.2 API applications.
Appendix A, Status Info, explains all the status info values that can be
returned by LU 6.2 API intrinsics.
Appendix B, Sample Programs, contains a sample transaction program,
in COBOL II and Pascal on the HP 3000 side, and in PL/1 on the IBM
side.
Appendix C, State Transition Tables, lists the intrinsics that can be
called from each state and the effect of each intrinsic on the state of a
conversation.
Appendix D, LU 6.2 Verb Table, maps the LU 6.2 architected verbs to
Hewlett-Packard’s LU 6.2 intrinsics.
Appendix E, Transact Parameter Masks, describes the parameter
masks used in Transact programs on MPE V systems.
Appendix F, Migrating Transaction Programs, provides information on
migrating LU 6.2 API applications from MPE V to MPE XL or from
earlier versions of LU 6.2 API/XL to the Node Type 2.1 version of LU
6.2 API/XL.
