Yep got it--several kind people pointed out that site to me and
I leeched quite a bit.  Lovelace, AdaTutr, and a hypertext
version of the RM.

[Snip -- informative info on Ada95 syntax for such things]

Yep all my books are Ada83 ones.  I'm definitely going to look
for some Ada95 books.

Hmmmm, well I managed to get it to work with Turbo C, but then I
had the MK_FP macro--but I think it all boiled down to shifting
the address.  I wasn't sure if that would cut it since my program
seemed to have some tie-ins to a memory manager so I wasn't sure
if some kind of mapping would occur that would obliterate any
hopes of manually doing something like that.  I know I finally
got the code to compile (thanks all), but running it resulted
in a Segmentation Fault.  Just like being on UNIX :)
