Writing programs for LUTYPE6.1 conversations

These topics describe the CICS® APIs available for DTP programming using LUTYPE6.1 conversations.

Conversation initiation
The front-end transaction is responsible for acquiring a session, specifying the conversation characteristics, and requesting the startup of the back-end transaction in the partner system.
Back-end transaction initiation
The back-end transaction is initiated either by an attach header received from the partner system or by a transaction name included in the incoming data, and is started with the session as its principal facility.
Transferring data on the conversation
These topics discuss how to pass data between the front-end and back-end transactions.
Ending the conversation
These topics describe the different ways a conversation can end, either unexpectedly or under transaction control.
Checking the outcome of a DTP command
Checking the response from a DTP command can be separated into two stages.
Considerations for the front-end transaction
Several special considerations apply to the front-end transaction in an LUTYPE6.1 conversation.
Summary of commands for LUTYPE6.1 conversations
The CICS application programming interface provides a set of commands for use in LUTYPE6.1 conversations.
State transitions in LUTYPE6.1 conversations
These topics show the state transitions that occur when transactions engage in LUTYPE6.1 conversations. The state transitions are presented in the form of a state table. The state table shows which commands a transaction can issue while the conversation is in any given state. It also shows how the conversation state changes as a result of any command.
