> What are the differences of Vax Ada and Ada 95?

VAX Ada conforms to the Ada 83 standard.

One major reason why there is no Ada 95 implementation on VAX is
that Ada 95 requires IEEE floating point semantics while the VAX
hardware provides VAX floating point semantics.

VAX Ada became DEC Ada became Compaq Ada became HP Ada and runs
on either VAX or Alpha, implementing Ada 83.

If you want an Ada 95 implementation on the VMS operating system,
use GNAT Ada 95 for Alpha VMS.  It has many of the VMS-specific
capabilities of the original VAX Ada.
