Also, you introduced another variable, ISPF (and I assume other software would
fit in as well), which I wouldn't have thought to include when trying to
compare the Linux kernel to the z/OS ... ? Nucleus is it called?
Plus the Linux kernel can be stripped down to bare necessities and the
executable size can be quite small.
Anyway, it was interesting to hear what people said about this topic, but now I
don't think it's very easy to compare Linux to Windows to z/OS without going
into specific details.

Once Upon A Time...
...it might have been true that the OS nucleus was the operating system
in what grew into z/OS. As my first exposure to this OS was an MVS 3.8
SE2 system that was on its way out at the time, I can't say. Today,
though, it's not so. These days, critical parts of the OS reside in
other data areas (e.g., (E)LPA) and data sets (e.g., linklib).
Anyway, I remain highly skeptical of any count of LOC being truly a
could of how many LOC there actually are, or how complex or large the
resulting "stuff" might be. Apples and coconuts both grow on trees;
this is almost like apples to asteroids. ;-)
