Error Handler

This handler may be either jumped to or called.

      ENTRY BADOPR
404   PRINT 406, PC
406   FORMAT(' BAD OPERATION, PC: 'O4)
      STEP=0
      RETURN

Does this work? Statement 404 is reachable from entry other than BADOPR. Can two entries share the same RETURN statement? The simulator may have never executed a bad operation to test this code.
