yes, true, but maybe if one has a firm grasp of how the control flow of
the program is
structured, some functions (user interface comes to mind) could be moved
to a separate
thread. This would require not a simple recompilation under Windows,
rearranging of the logic of the program.

Those functions do exist under Windows, but maybe here also a splitting
of the screen in
more than one window could be useful, e.g. keep the menus in a separate
window, the waterfall
in another, and so on. This breakdown of the user interface needs too a
of the structure of the program.

I should have used a different wording, sorry... what I meant is
precisely what you
mentioned, i.e. comments at the instructions level, which could be of
help in better
understanding how the program works.

Architecture is just a fancy word to indicate the program structure,
what is the flow of
control of the program, what the dependencies are, etc. etc. In other
words, all what
is needed for a person who didn't write the code to understand what it
more important, how it does it.
Thanks for your answer Leif. I will study the source code to see if I am
able to understand
from it what mentioned in the previous paragraph.
