Dear Experts

I want to zap following three dbf's, if no error occurs.
I mean if database not found or any dbf is corrupt then EXIT.
In other case, if database found and dbf's are OK then given dbf's should ZAP.

CLOSE ALL
CLOSE DATABASES ALL
OPEN DATABASE cFolder2+'\TABLES\ACCOUNT.DBC' EXCLUSIVE
USE vouchers 
ZAP
USE VOU_SUM 
ZAP
USE VOU_NO 
ZAP

Thanks in advance
