$WSC mapping

         The rules for counting initiators and executings
         batch jobs as a consequence of a $TJnnn command
         are as follows:
              o If a job was selected by a WINIT (WLM
         Initiator), it is forever going to be included
         when counting active jobs for a service class.
              o If a job was selected by a JINIT (JES
         Initiator), it is forever not included when
         counting active jobs for a service class.
              o If an executing job's service class is
         changed from one class to another via a
         $TJnnn,SRVCLASS=something (something can be all
         blanks) or a RESET MVS command and the job was
         selected by a WINIT, then the job will be removed
         from the original service class count and added to
         the new service class count (and the initiator
         count will be changed similarly). The job count
         can take as long as 30 seconds to be updated. The
         initiator count is instanteneous.
              o If a characteristic of an executing job is
         changed (something that influences the service
         class assigned to the job), then nothing will be,
         done to alter any counts. The service class is
         not changed until and unless the job re-executes.
              o If a job's job class is changed to a
         different class and that class has the opposite
         mode of the original class (original was MODE=JES
         and new has MODE=WLM or vice versa), there will be
         no changing of active job count (If the job
         started as a WINIT job, it stays a WINIT job; if
         it started as a JINIT job, it stays a JINIT job).
