Basic Conversation Verbs

The basic conversation verbs are intended for use by LU services programs. The LU

services programs can provide end-user services or protocol boundaries for end-user

application transaction programs. For example, the mapped conversation LU services

component issues basic conversation verbs during its processing of mapped

conversation verbs.

Not all verbs from all the IBM option sets have been implemented. The table below

shows a list of the basic verbs currently supported.

The REQ-UOW-CODE field values for the basic verbs are the same as the

corresponding mapped verb UOW-CODE minus 100. For example, ALLOCATE is

1001 and MC-ALLOCATE is 1101. The values for all 12 verbs are also shown in the

table below:

While the REQ-UOW-CODE varies from verb to verb, the REQ-UOW-ID is still ST to

mark the beginning of each UOW.
