A command prefix value that was specified as input to the subsystem ssname is not valid. The prefix value is either greater than 8 characters, begins with an incorrect symbol, or contains an imbedded blank.
Subsystem initialization continues. The system ignores the specified command prefix value and uses subsystem name ssname as the default command prefix.
If the default command prefix is unacceptable, enter a CANCEL command prefixed by ssname to cancel the subsystem immediately. Then, if you entered the incorrect command prefix as a parameter on the START command when you first started the subsystem, re-enter the START command to restart the subsystem with a valid command prefix value.
If you did not specify the incorrect command prefix on the START command, notify your system programmer.
If the incorrect command prefix was specified as a parameter in the job procedure that was used to start the subsystem, correct the command prefix parameter in the procedure so the system will use the correct command prefix the next time the subsystem is started.
