The SET_TRANSACTION call
The SET_TRANSACTION function is provided on the DFHXMIQX macro call. Its
purpose is to allow you to change the task priority and transaction class of the
current task.
Note that you can use this call to change the TCLASS_NAME only when it is
invoked from an XXMATT global user exit program.
