Data received from an application is issued as line messages to the environment that last issued an MAI-OC command against that session. For example, if you issued an MAILOGON command from OCS, then the initial application messages resulting from the session establishment are received by the OCS environment. If the next MAI-OC command for that session is from a dependent environment, for example MAISEND through $CMDENT, then further messages are returned to the dependent environment.
Application data is displayed unchanged, with the possible addition of some information before the text. This information is the session identifier of the session from which the data was received. For example:
(CICS) H2002I TERMINAL CONNECTED
The presence of the prefix information and its format is controlled by options specified on the MAILOGON command.
The messages may be in response to a command or NCL system variable that was issued, or they might be unsolicited information, depending on the way the application functions. However, all messages are flagged as unsolicited.
Note: The PROFILE UNSOL=NO command does not prevent the receipt of messages generated by an MAI-OC session.
