SUMMARY
=======

The Help file for Visual FoxPro has an incorrect code example for the SET KEY
command. The RANGE clause is omitted, and the SET ORDER TO command refers to a
field that does not exist in the Customer table in the Testdata database.

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.
