No, PFKs and the like are not OOP, whether physical or virtual. However, the GUI that implements them could well be OO.
There are no functions in pure OO programming, although class methods come close. -- Shmuel (Seymour J.)

And how about a online transaction, where one screen updates a particular table in your overall system. And the different transaction ids would be like an Object / function. Just leaves the batch job to use structure programming, because you are dealing with a whole file at once.
