>If a cursor is created with Create Cursor, the resulting cursor is editable. However if the cursor is created with a SQL-Select, the resulting cursor is not editable. Is there a way to make the later editable?

John,
Yes you can do it with a little code up to VFP7. VFP7 has a new clause 'readwrite' to do it directly.
First be sure it's a true cursor :
-In fox2x either having a nonexistant field or an expression in where could force it to be. ie:

select * from myTable where .t. into cursor MyCursor

-In VFP there is 'nofilter' clause
select * from myTbale into cursor myCursor nofilter

Next use it again.

select * from myTable into cursor crsTemp nofilter
use dbf('crsTemp') in 0 again alias crsRW
use in 'crsTemp'
select crsRW
