 Low level features in GNAT on DOS?


Does GNAT on DOS support low level features such as

        - for object'address use <some value> ?

        - the ability to call the DOS interupt functions, e.g. Interupt 16#16#,
function 0,
          which reads the raw scan code from the keyboard.

        - the 80x86 IN and OUT instructions?

...and how would I go about using them?

Specifically I would like to convert some old code that writes directly
to video
memory (80x25 mode), and be able to read characters raw.
