In VFP7 ALTER TABLE doesn't work on cursors with field names longer than 10 characters.

>In the tips in the back of the Sept 2002 UT magazine :

>Sometimes, you may want to add some fields to a cursor. Assuming, you have created your cursor in READWRITE mode, you could do the following:
>
>ALTER TABLE 'temp' ADD COLUMN cImage c(20)
>
>Since this mentions readwrite I assume it refers to a cursor created with a SQL Select
>
>SELECT ccompany FROM cutomer INTO CURSOR temp READWRITE
>ALTER TABLE 'temp' ADD COLUMN url m
>
>When I do this I get an 'Invalid operation for the cursor' message.

>I was hoping this would be a shortcut around the old dummy cursor Cartesian join trick. What am I missing?
