Cursors that are created by the INTO clause of a SELECT command are by default not updateable. In order to make them updatable you can:

USE DBF('nameofcursor') AGAIN in 0 ALIAS someothername

then make the changes to that work area.

The updatability that you are referring to in you question has to do with making changes to a view cursor and having those changes reflected back in the underlying (original) tables.

>>Then look at the help for CURSORSETPROP. You can pass several parameters, but the first parameter is the property of the cursor you want to set. You will need to set several properties including Tables (the tables you will be updating), UpdatableFieldList (the fields that you want to be able to update), KeyFieldList (which fields are key values so the update can find the right record to update), UpdateType, and WhereType. There may be some other options you want to set, but I think this is the core set. Basically it sets the same properties that you would set visually when you design a View.
