'C' for CP/M

[Dr. Ted Carnevale]

I would like to mention C/80 by Software Toolworks.  It was far from 
standard, but not as far as BDS C.  Produced more compact code than Aztec C
or Eco C, and it compiled faster than them (but a bit slower than BDS C).
Somebody named Gustafson wrote a rather complete set of library routines for
it that he marketed under the name of Viking Software (or something close
to it).  Very nicely done.
C/80 produced assembly language source suitable for ASM, but with a command
line switch it would make code for M80.  SLR Systems assemblers and linkers
were also usable.
