That's indeed probably true.

That's a non sequitur:
a) even though the original code was written a long time ago, it has
been changed many times since then
b) if it isn't broken, don't fix it. Example: changing all occurrences
of "string" into "shortstring" will break the system unit. The reason
is that a "var a: string" is an "openstring" parameter (with a hidden
"high" parameter that tells you the size of the variable that was
passed in), while "var a: shortstring" is not. So at the very least,
you'd have to change var/out parameters into openstring rather than
Adding support for new functionality (such as unicode file names)
would obviously require revising all of that code, but that's because
the context changes rather than because it's old.
