Example

open database southwind
select * from shippers into object shipobj
print_r(shipobj)
Dynarray (refcnt=1)
(
    [row1] => Dynarray (refcnt=1)
        (
            [shipperid] => 1
            [companyname] => Speedy Express
            [phone] => (503) 555-9831
        )
    [row2] => Dynarray (refcnt=1)
        (
            [shipperid] => 2
            [companyname] => United Package
            [phone] => (503) 555-3199
        )

        )

class NullData dynamic
    property mCHARACTER
    property mNUMERIC
endclass
 
oNULLDATA = new NullData()
oNULLDATA.mCHARACTER = ""
oNULLDATA.mNUMERIC = 0
oNULLDATA.mLOGICAL = .F.
print_r(oNULLDATA) // or alternatively just echo oNULLDATA
