Peter,

If Customer.dbf table is in use with another alias name, use customer would be cause error "File In Use" unless you include AGAIN keyword. Additionally, in a multi-user environment if anyone else has customer.dbf open exclusively, you would get error "File access denied" whether you try to open it exclusively or shared. If another user has it open shared and you try to open it exclusively, you will get error "File access denied".

Also the syntax

if not used('customer.dbf')

would always return .t. since used function is expecting an alias name.

At least that is how it works in VFP6 SP5
