Condition_Values_Returned

   SS$_NORMAL         Normal successful completion. The user output
                      routine has completed the function that the
                      symbiont requested.
   PSM$_FUNNOTSUP     Function not supported. The user output
                      routine does not support or does not recognize
                      the function code supplied by the symbiont.
                      To ensure future compatibility, your output
                      routine should return this status for any
                      unrecognized status codes.
   PSM$_PENDING       Requested function accepted but not completed.
                      Your output routine can return this status
                      only with PSM$K_WRITE and PSM$K_WRITE_NOFORMAT
                      function calls. Further, if your routine
                      returns PSM$_PENDING, your routine must
                      eventually signal completion by way of the
                      PSM$REPORT routine. Refer to the description
                      of the PSM$REPORT routine for more information
                      about asynchronous write operations and the
                      PSM$_PENDING condition value.

   This routine also returns any error condition values that you
   have coded your output routine to return.
