I am trying to gain a better understanding of what happens with SELECT INTO CURSOR. If I issue a command such as

select * from somefile into cursor crsTemp

It appears that the original file (somefile) is opened by the OS although it is not technically USED. Is this correct? If yes, then what do we have to do to close the file so that it is available to other programs or so that it can be overwritten? I have tried to

use in crsTemp
copy to somefile

but I still get an error that says the file is open. Can someone shed some light on this?

Thanks
