AFAIK it's ok to use the AGAIN clause. I would personally use something like this:

llUsedCustomer=Used('customer')
If Not llUsedCustomer
    Use Customer In 0
Endif
... program code
If Not llUsedCustomer And Used('customer')
    Use In Customer
Endif

Much more organised.


>Does anyone know if there's any harm in adding "AGAIN" where it's not needed? IOW, if the table is not open in any work area and you say USE < table > AGAIN IN 0, is there any extra overhead, any problems, or is the AGAIN clause just ignored?
