I'm afraid that there is no such animal. The actual number returned by pressing
Alt+d on an IBM style PC keyboard is OEM specific and depends on the program
you are using. Correct me if I'm wrong, but I believe the Mac doesn't even have
an Alt key. When I program, I have to specifically check the language's
information in order to find out what will be returned on pressing non-ASCII
key-combinations. For example, Foxpro for windows uses 288 to represent Alt+d,
while Visual Foxpro (brought to us by the selfsame Microsoft) returns 32 from
the inkey() function if I press Alt+d (same as a space but distinguishable
because Alt+<Space> returns 57). I don't remember what Clipper returned, and
C++ pretty much depends on the Windows API.

I know this is not really helping you a whole heck of a lot, but I just figured
you'd better know what you're up against if you intend to insert non-ASCII
codes into what purports to be an ASCII document.

The ASCII codes run from 0 to 127, and represent keypresses that can be handled
by any ASCII compatible system. They represent all the "normal" printable keys,
the escape key, and the letter keys in combination with the control key to
allow for cursor movement and the infernal beep. The Alt key is simply not part
of the ASCII standard.
