  We have some experience with both fort and f77 (on uVax II's).  Re bugs and
  speed:
   fort does not compile any faster (maybe a bit slower, in fact). But it does
   execute much faster in computation-intensive applications.  Ratio apx.
   2 - 3 : 1 .
   A "few bugs" may be an understatement.  Has anyone had any positive exper-
   iences getting help with these from DEC ??
