PCAA> SET EDITOR/CALLABLE_LSEDIT/START_POS "LSEDIT/READ_ONLY"

      This command causes subsequent EDIT commands to invoke callable
      LSEDIT with the default command line of LSEDIT/READ_ONLY. Also,
      the /START_POSITION qualifier will be appended to the command
      line, causing the editing session to start on the source line
      that the Analyzer is currently pointing to.
