Not wanting to be a nuisance, but...

If the table is already opened 'shared' as another alias in another work area or in another 'datasession' then won't this code fail? Does this mean that mean that another user has it open :-)

No, I don't have a better answer :-)

(and yes, its my last day before a holiday, so I'm in a silly mood)

>>How do you check if a file is opened exclusively somewhere else (on another machine)? ISEXCLUSIVE() doesn't seem to be the answer.
