>You have to use ALIAS or it will reopen the table with A, B. C... aliases. You can open it ALIAS mytable if you want to use the tablename. It would be much more complex if you want to use any existing alias for that table that may happen to be open, but that's time for a redesign IMHO.

I think we're drifting from the original problem. The original problem was to check if the particular table is opened under any alias. Your code (without again) will work, e.g.

Local llMyTableOpened

>llMyTableOpen=.F.
>Try
>	Use mytable Alias UsedJustToCheck  in 0 shared
>Catch

   use in select('UsedJustToCheck')
