Hi Ric,

You could do something like:

LOCAL lError, cError

lError = .F.

* ----- Store current Error Handler
cError = ON("ERROR")

* ----- Set new Error Handler
ON ERROR lError = .T.

SELECT 0
USE filetopack EXCLUSIVE

* ----- Reset Error Handler
ON ERROR &cError

IF lError = .T.
   * ----- Table couldn't be opened Exclusively
   *       Display appropriate Error Message
ENDIF

Hope This Helps,
Gavin...
