If I execute the following statement with no databases active:

SELECT * FROM mytable INTO CURSOR mycur

and mytable.dbf is a table contained in database mybase.dbc then the "database" property of the resulting cursor will be:

1) blank if DELETED is ON, or
2) "mybase.dbc" if DELETED is OFF

I discovered this because, in the respective cases, the following statements:

SELECT mycur
INDEX ON myfield TAG mytag

1) create a temporary .cdx which VFP automatically
deletes on exit (good!!)
2) gives an error saying that the related .dbf is read-only(bad!!) (presumably because it's trying create the index in mytable.cdx)

I am unable to find any documentation that describes this behavior.
Can anyone explain what's going on or point me to documentation that will shed some light?
