Hi Richard,

The word Cursor... Stands for Current Set Of Records

In basic terms.. it's a temporary table, when you close it, it vanishes.

Sometimes they are read only (Created from a SQL statement)
Sometimes they are read-write (Created by Create Cursor)

Sometimes a cursor exists on Disk,
Sometimes it only exists in memory.. Foxpro decides (depending how big it is).

There are various tricks to force cursor's into read-write mode and force it to exist on disk but I won't go into them unless you want me to :)

HTH

Will
