ISBLANK(quantity) is returning .F. for these blank values. The records were originally created with INSERT INTO mytable (someotherfield) VALUES(someothervalue). Of course, neither this command nor any other one specified the value of the quantity field.

I just tried APPEND BLANK and then BLANK FIELDS quantity. The expression ISBLANK(quantity) returned .F. after each of those commands.
