2.1.2 Conversation Verbs
Conversation verbs enable TPs to allocate a conversation, send and receive data, change conversation states, and
deallocate a conversation.
The following verb can be issued in either a basic or mapped conversation:
• GET_TYPE
Most conversation verbs fall into two groups:
• Mapped-conversation verbs, which a TP can issue only in a mapped conversation
• Basic-conversation verbs, which a TP can issue only in a basic conversation
Conversation verbs are grouped by type, mapped or basic, as shown in Table 2–1, Mapped and Basic Conversation
