Hi Steve,

But if you leave off the table name (isblank(cField)), it works correctly.

I test on VFP6 and give costant value.

CREATE CURSOR PirillinoDelPicchio (a i)
APPEND BLANK
INSERT INTO PirillinoDelPicchio values(1)
INSERT INTO PirillinoDelPicchio values(2)
GO TOP

SELECT a,ISBLANK(a) FROM PirillinoDelPicchio

* 0,.F.
* 1,.F.
* 2,.F.
