VAX FORTRAN support for these types was there as soon as the types
existed. You had to choose between D and G formats for your double
precision type. REAL*16 was always H.

Also, I didn't see anything about library support for D vs. G.
Did the compiler automatically call the right library routine
for the appropriate type?

You mean such as math routines? Yes, of course. You had to use a
compile-time switch (or a directive in the source) to select between D and G.
The difference was largely transparent to the user, except when you made the
mistake of passing a single to a routine that accepted a double (as noted in
this thread.)
