Similar to Chip's post based on the age of Excel I would have to say the
original code would have been C. However based on the current architecture of
Excel I would have to say the majority of the code would now be object
oriented so C++ would be the order of the day (The properties and methods
model is kinda obvious at this point). As to whether all of the code it
object oriented (since C++ will compile procedural C code) it is hard to say
whether the entire thing would be OOP.

This is all just idle speculation on my part...

Out of shear morbid curiousity, I'd like to know what programming language
Excel is written in. I would usually guess Visual C++, but since it is so
steeped in VB, I'm not sure.

Anybody have a clue?
