I found the problem. There was an endless loop.

>Hi All,
>I have a cursor named "toplamlar" which created with select command. A scan...endscan block uses that cursor and there are another methods in that block. At endscan line it gives "file not open" error. I can run "select toplamlar" before or after endscan so it means toplamlar open yet. I tried use nofilter with select command, no success.

>At last I used old do while loop with skip command and there is no problem now. I wrote that message for just curious. Why that error generated?
