DOCERR: Incorrect Syntax in SET KEY Command Example in Help

MORE INFORMATION

Following is the incorrect code example for the SET KEY command:

   CLOSE DATABASES
   USE customer
   SET ORDER TO zip
   SET KEY TO '43000', '43999'
				

This code example returns an error because there is no Zip field in the Customer table. If the Zip field did exist, the only records visible would be those with a value of 43000 in the Zip field. This is because there is no RANGE clause in the SET KEY command.

Following is the corrected code example:

   CLOSE DATABASES
   USE C:\VFP\SAMPLES\DATA\Testdata!Customer
   INDEX ON postalcode TAG postalcode
   SET ORDER TO postalcode
   SET KEY TO RANGE '40000', '43999'
   BROWSE
				

Using this code, you will see records that have values between 40000 and 43999 in the Postalcode field.
