DFS3618 SPECIFIED COMMAND RECOGNITION CHARACTER (CRC) NOT FOUND

Explanation
 The command recognition character (CRC) specified
on the /SSR command was either not defined to IMS or
incorrectly specified on the command. Therefore, IMS could
not associate it with an external subsystem.

System action
 The command is rejected.

Operator response
 Notify the installation personnel about the
receipt of this message to ensure that you have the correct CRC for
the subsystem. Then reenter the command.

Programmer response
 Ensure that the CRC defined for the external
subsystem is correct in the external subsystem PROCLIB member entry.
