RE: Simple Display file problem

SQL's set based nature allows for some very elegant solutions.  Display 
programs are a perfect fit for SQL cursors.  I only wish IBM would 
implement the ability to position on data values within a cursor.

Try doing something like this using RLA.  The file contains zipcodes and 
lat/long values.  STRQM will prompt the user for &zip and &mileage when it 
is run.

SELECT B.ZIPCODE AS ORIGINALZIP, A.ZIPCODE AS DESTINATIONZIP,
       CAST(SQRT( POWER(ABS(A.LAT-B.LAT)*69.1,2) + 
                  POWER(ABS(A.LONG-B.LONG)*53,2) ) AS DEC(5,2)) 
        AS MILEAGE
FROM BS660F AS A 
 INNER JOIN 
     BS660F AS B 
  ON SQRT( POWER(ABS(A.LAT-B.LAT)*69.1,2) + 
           POWER(ABS(A.LONG-B.LONG)*53,2) ) < &MILEAGE 
WHERE B.ZIPCODE = &ZIP 
ORDER BY MILEAGE DESC
