How to check if normal successors are prevented from running

The SU£ column shows if the job displayed under the JOBNAME column has a normal successor. If the number displayed in the SU£ column is 0 then that job has no normal successor, and, even if the operation ended in error, no successor job is prevented from running. If the number displayed under SU£ is greater than 0, then the job has a normal successor that is prevented from running because its status can be set to Ready (R) only if the predecessor job status is Complete (C) or Suppressed by condition (X).
