>Yes, it's the way SQL select works in foxpro. You can use USED() function to check if a table is already open
IF NOT USED("mytable")

>SELECT Mytable

Faster with: USE IN SELECT("MyTable")

You can also keep the table open, and USE AGAIN.

I colect some data from a free table with a SQL command (SELECT * FROM mytable INTO CURSOR c1) I can get other data from the same table with SQL command into other cursors (c2, c3, ...) but I can't open my table with the USE command, I get error 'File in use'
