MVS is not written in assembler, it is written in PL/S, a C-like
language which looks like PL/I.  code generation is about as good and
allows direct access to anything that can be accessed from assembler.
the size is dependent upon what you consider to be the operating system
executable.  a estimate for the minimum neccesary to do useful work
would be about 6 or 7 Mbytes.  about 3Mbytes of this is microcode.

VM would be about 600,000 lines for all components and is written in
assembler, occupying about 600K.
