DOCERR: Incorrect Syntax in SET KEY Command Example in Help

ID: Q139185

3.00 WINDOWS kbref kbdocerr

The information in this article applies to:

Microsoft Visual FoxPro for Windows, version 3.0

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.
