Conversation Type and Style

The conv_type parameter is used to determine both the conversation type and conversation style of the program to be started. The conversation type attribute determines whether the program to be started supports basic or mapped records when it sends and receives data. The conversation style attribute determines whether the program to be started supports half-duplex conversations. The attach manager checks whether a transaction program uses basic or mapped verbs and if it uses half-duplex or full-duplex.

The conversation types are:
BASIC
The transaction program issues only basic conversation verbs for its conversations.
MAPPED
The transaction program issues only mapped conversation verbs for its conversations.
EITHER
The transaction program issues either basic or mapped conversation verbs for a conversation, depending on what arrives on the incoming allocation request.
The conversation styles are:
HALF
The transaction program supports half-duplex conversations only.
FULL
The transaction program supports full-duplex conversations only.
EITHER
The transaction program supports either full or half duplex conversations.
