 NAME - MRSCLIOP
 DESCRIPTIVE NAME - Monitor Event Record
                    Domain 2 - Scheduler Domain
                    Record 11 - I/O Priority Change
 DESCRIPTION - Records I/O Priority change to a user.  A
               user's I/O priority may change when a system
               change occurs.  A system change occurs when
               the system operator changes the I/O priority
               status on the system console.  A user change
               can also occur when a SET IOPRIORITY command
               is issued specifying this user, or user logs
               on and has a IOPRIORITY directory statement.
               This record is generated only if the user
               who is the target of the command is enabled
               for scheduler domain (not to be confused
               with the user that issued the command).
