Well, if you want to count it that way, consider that the first release
of MVS was written largely in PL/S. For those who don't know, PL.S was
an IBM internal language that was very much like PL/1, but when
compiled, produced assembler source code which was then assembled as the
second stage of the "compile" process. The MVS development standard,
which I co-authored, required that you needed a special standards
deviation to write a complete module in assembler. I had to justify a
performance xoncern in order to write my original quickcell modules in
assembler and got the deviation for performance reasons.
Maybe if you compared PL.S lines to C/C++ lines, you might get closer
to grapefruit to oranges :-).

assembler (you said original MVS) ¬= C/C++ lines of code or generated

My googlinging didn't tell me much about z/OS. Any even close semi-ballpark idea how
many lines of code are in the z/OS operating system? (Or even a "standard"
serverpac distro?)
