While this is true, it is unlikely that a future version of Delphi would
introduce a pointer size that is smaller than an integer, so the above code
ought to work - in any case, you can always declare an explicit sized
integer (say 32-bits) and assume that future versions of Delphi will not
have pointer sizes less than 32-bits.

This I don't necessarily agree - it might be the best option for a quick and
dirty hack, but if I was to design the application, I would use an business
object model and make the combobox list a view of the data only - so your
business logic code is not dependent on the UI.
