/PREDECESSOR={script-name}
       /NOPREDECESSOR (default)

          The /PREDECESSOR qualifier identifies the name of
          the script that precedes the execution of this script
          in a linked set of scripts. These scripts execute in
          sequence; one successfully completes before the next
          one begins.

          The predecessor script name must exist in the
          scheduling database or an error status message is
          returned. You can use wildcards in the script-name
          specification. Use an asterisk (*) to take action on
          all scripts on the VAXcluster system; use a percent
          sign (%) to match a single character in the script-
          name specification.
