That's because you told it to open nothing in the SELECT('Schedule') workarea. You could likewise

USE AnyOtherTable IN (SELECT('Schedule'))

and it would open AnyOtherTable in the workarea SELECT('Schedule') (which would be the first unused workarea if Schedule is not used). Since nothing is stopping us from opening the same table where it was already open...

USE schedule IN (SELECT('Schedule'))

would open Schedule in the workarea SELECT('Schedule').

So it closes and it can also open - that's the dual nature of the USE command, available since dBaseII, IIRC.
