CMSSL — Set_Sync_Level


CMSSL (conversation_ID, sync_level, return_code) [LOGGING log_byte]

Where

conversation_ID (character input) specifies the conversation identifier of the desired conversation.

sync_level (numeric input) specifies the synchronization level that the local and remote programs can use on this conversation. The sync_level can have one of the following values:

CM_NONE
CM_CONFIRM

Note: WSim does not support the sync-point synchronization level.

return_code (numeric output) specifies the result of the statement execution.

log_byte is a 1-byte string constant or a string expression that specifies a byte of user data to be associated with this CPI-C statement during logging. The log_byte remains active until another CPI-C statement is issued. Only the first character or first two hexadecimal digits of the string expression are used. The default log_byte is X'00'.

Function

A program uses the CMSSL statement to simulate the CPI-C CMSSL call, which is used to set the sync_level characteristic for a given conversation. The sync_level characteristic is used to specify the level of synchronization processing between the two programs. WSim supports either no synchronization or confirmation-level synchronization (using the CMCFM or CMCFMD statements). The CMSSL statement overrides the value that was assigned when the CMINIT statement was issued.

Note: The CMSSL statement can be issued only after theCMINIT for the conversation has completed, and before the CMALLC is issued.

For more information on CMSSL and its parameters, refer to the Set_Sync_Level (CMSSL) call description in the “Call Reference” chapter of Systems Application Architecture Common Programming Interface Communications Reference.
