DIRECTIVE:  {$R.}

      DEFAULT STATE:  R-

      DIRECTIVE RANGE:  Local

      COMMENTS:   Turning range-checking on generates code that
                  checks operations to insure they are within their
                  specified range.  If they are out of range a runtime
                  error message will be displayed and the program will
                  terminate.  With this directive on the program will
                  be larger and slower, therefore it is best to place
                  range-checking on during the debug stage and range-
                  checking off during the final compile stage.
