Update Record In A Cursor

Please tell me how to code the Update of the current cursor record as one would do using VD/ADO :

VB: Table("Fieldname") = Value

----------------------------------------------------------
Declare @NextNo integer
Select @NextNo = (Select NextNo from NextNumbers where NNId = 'AddressBook') + 1

--Create a Cursor through wich to lo loop and Update the ABAN8 with the corrrect NextNo
DECLARE Clone_Cursor CURSOR FOR Select ABAN8 from JDE_Train.trndta.F0101_Clone
Open Clone_Cursor
Fetch Next from Clone_Cursor
WHILE @@FETCH_STATUS = 0
BEGIN
Select @NextNo = @NextNo + 1
Clone_Cursor("ABAN8") = @NextNo
Update Clone_Cursor
FETCH NEXT FROM Clone_Cursor
END

CLOSE Clone_Cursor
DEALLOCATE Clone_Cursor
GO
