A simple workaround for this VFP behaviour
( i see it on other SELECT context, but i do not remember if i have open a thread on past time ):

CREATE CURSOR Walker (II I NULL)

INSERT INTO Walker VALUES (2)
INSERT INTO Walker VALUES (NULL)
INSERT INTO Walker VALUES (NULL)
INSERT INTO Walker VALUES (NULL)
INSERT INTO Walker VALUES (1)

SELECT;
 (Cur1.II) AS II1,;
 (Cur1.II) AS II0,;
 Cur1.II AS II2;
 FROM Walker AS Cur1
