3 Using Intrinsics
Chapter 2 , “Conversations,” introduced the types of conversations in
which transaction programs can participate. This chapter explains how
LU 6.2 API intrinsics are used to create the conversations described in
Chapter 2 , “Conversations.”
Table 3-1 lists the intrinsics that will be discussed in this chapter. The
list is a subset of the LU 6.2 API intrinsics. Chapter 5 , “Intrinsic
Descriptions,” contains a complete description of all of the intrinsics.

Intrinsic Definition
MCAllocate Establishes a mapped conversation between TPs.
MCConfirm Sends a confirmation request to the remote TP and waits for a reply.
