   My first 11/780 was running VMS 1.x, and lots of things were in
   compatability mode.  Don't know about the compiler.

   My next 11/780 arrived at the time of VMS 2.2, and lots of things
   were still in compatability mode, but DEC told us the only two
   native compilers were Fortran and COBOL.

   We started interfacing Fortran routines with Macro-32 routines right 
   away, so I don't think the compiler could have been generating
   PDP-11 object, although it could have had heritage to a
   cross-compiler from RSX (running in compatability mode but generating
   VAX object).

   I just recall the day I got the last programmer off SOS and on to
   EDT, and the CPU load went way down.  Seems SOS must have been quite
   a compatability mode CPU hog.
