Hi,
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.
Dale
