      * RTVJOBCNT: Retreive job count
      * This program retrieves details of the input job and returns the number of matching jobs
      * The user space header provides the number of entries returned - if this is zero,
      * then no matching jobs were found. If jobs are found, then their details are pulled out of
      * the user space. Currently the job details are not used.
      *
      * Note: The input parameters to this program are passed direct to QUSLJOB, so should match
      * what it expects. The following is an extract from IBM's List Job (QUSLJOB) API documentation
      * See <http://publib.boulder.ibm.com/iseries/v5r2/ic2924/index.htm?info/apis/qusljob.htm>  
      * ============================================================================================
      * Qualified job name INPUT; CHAR(26)
      *
      * The name of the job to be included in the list. The qualified job name has three parts:
      *
      * Job name CHAR(10). A specific job name, a generic name, or one of the following special
      *                     values
      * *            Only the job that this program is running in.
      *               The rest of the qualified job name parameter must be blank.
      * *CURRENT     All jobs with the current job's name.
      * *ALL         All jobs. The rest of the job name parameter must be specified.
      *
      * User name CHAR(10). A specific user profile name, a generic name, or one of the following
      *                     special values:
      * *CURRENT     Jobs with the current job's user profile.
      * *ALL         Jobs with the specified job name, regardless of the user  name.
      *               The rest of the job name parameter must be specified.
      *
      * Job number CHAR(6). A specific job number or the following special value:
      * *ALL         Jobs with the specified job name and user name, regardless of the job number.
      *               The rest of the job name parameter must be specified.
      *
      * Status INPUT; CHAR(10)
      *
      *    The status of the jobs to be included in the list. The special values supported are:
      *    *ACTIVE      Active jobs. This includes group jobs, system request jobs, and 
      *                  disconnected jobs.
      *    *JOBQ        Jobs currently on job queues.
      *    *OUTQ        Jobs that have completed running but still have output on an output queue.
      *    *ALL         All jobs, regardless of status.
