This is the first of four topics detailing the CICS® APIs available for DTP programming.
The different APIs are compared in Concepts and design considerations.
Part 2 contains:
This advises you how to use the EXEC CICS API to write distributed transactions that use APPC mapped conversations.
This discusses the state transitions that occur when transactions use APPC mapped conversations under the EXEC CICS API. The state transitions are presented in the form of state tables showing which commands can be issued while a conversation partner is in any given state. The tables also show how the conversation state changes as a result of issuing a command.
