Writing a Transaction Program

This chapter describes issues to consider when planning and writing transaction programs to APPC. When developing a transaction program, you must choose between certain design alternatives. The following list describes the design issues to consider:

• Choosing either basic or mapped conversations
• Choosing either half-duplex or full-duplex conversations
• Deciding whether to start conversations with or without confirmation
• Using the security features
• Providing for conversion of ASCII names and data (if necessary)

The first part of this chapter provides background information on the application protocols, conversation states, Personal Communications support tasks, and data formats. The rest of this chapter describes specific requirements for developing a transaction program.
