Jim,

so it's still in the current (?) Fortran standard. How do those vendors
like Cray get by that force REAL=DOUBLE PRECISION=64 bit, like on the T3E?

Best regards

Hans-Christian mentioned :-

And Fortran95 too :-

   A scalar object of type default integer, default real, or default
   logical occupies one numeric storage unit. Defaul complex and
   default double precision real values occupy two consecutive numeric
   storage units.

I don't see this being removed from Fortran until both COMMON and
EQUIVALENCE are also removed...
