   That was a mistake, as others have pointed out.

   *shrug* Oh well, that is very scientific evindence, statistically   
   proven.   
      
   Counterpoint: On the University workstations I worked on, Fortran   
   was very much in use.  People wrote code to run on IBM mainframes   
   and ported this to the HP workstations.  Plus, there were vector   
   computers where REAL also was 32 bits.   
      
   Whose anecdotal evidence counts more.

   New flash:  Engineers rarely use Usenet (I'm a bit of an exception   
   there).
