Yep, on that point we agree. :-)  I did always think the exception 
handling being able to handle things at the hardware interrupt level was 
cool in Ada.  Just not cool enough to justify the memory usage of 
machines 20 years ago (which is nearly when I learned it, doesn't seem 
possible it was almost that long ago).

Very likely that is what I did.  Either that or I did inline assembly 
since my compiler supported that option.  I used information/techniques 
from the books Undocumented DOS (1e) and the Abacus book on DOS 
programming.  Still have both of those on the bookshelf at home.
