 From the above-referenced comp.os.vms posting . . .

Back in 2007, I wrote . . .

"This item code will first appear in OpenVMS I64
V8.3-1H1, expected to ship some time in the fall of 2007."

and

"This item code has been backported to V7.3-2, V8.2, V8.2-1, and V8.3, and
will require future SYS (for $GETDVI) and DCL (for F$GETDVI) kits.  There will
be no backport for the RTL routine LIB$GETDVI."

Back then, I was somewhat fanatical about backporting stuff to V7.3-2 as much
as possible.
