The abend S0C4 usually occurs when the JCL statement:
//OPS$OPSG DD DUMMY
used to specify the name of the OPS/MVS subsystem defined, references a wrong subsystem name.
The string 'OPSG' should be replaced by the OPS subsystem name defined during the installation. If the default value for the 'SUSSYSNAME' OPSPARM is used, then the above DD statement could be removed.
