   According to Anton Ertl :   
   >On the PDP-11 C's int is 16 bits.  I don't know what FORTRAN's INTEGER   
   >is on the PDP-11 (but I remember reading about INTEGER*2 and   
   >INTEGER*4, AFAIK not in a PDP-11 context).  In any case, I expect that   
   >FORTRAN's REAL was 32-bit on a PDP-11, and that any rule chain that

   I wrote INFort, one of the two F77 implementations for the PDP-11.   
   INTEGER and REAL were the same size because that's what the standard   
   said, and any program that used EQUIVALENCE would break otherwise. If   
   you wanted shorter ints, INTEGER*2 provided them.   
      
   Bell Labs independently wrote f77 around the same time, and its manual says   
   they did the same thing, INTEGER was C long int, INTEGER*2 was short int.   
      
   If the speed difference mattered, it wasn't hard to say something like   
      
         IMPLICIT INTEGER*2(I-N)   
      
   to make your ints short.
