             Technical Work on Ada 2005 Standard Completed

                         Formal approval by ISO
            (International Organization for Standardization)
                          expected by Q4 2006


PORTO, Portugal (June 6, 2006) -
On the occasion of the 11th Ada-Europe Conference on Reliable Software
Technologies, Ada-Europe, the international organization that promotes
the knowledge and use of Ada in academia, research and industry in
Europe, reported on the completion of the technical work on the new Ada
2005 standard and its steady progress towards formal approval by ISO,
the International Organization for Standardization.

The first of the three steps of the ISO standardization process has
been successfully completed. The Working Group in charge of the
technical details of the standard, named WG 9 and headed by the
convener Mr. James Moore, unanimously approved the Ada 2005 standard on
May 1st, 2006. Delegations of Belgium, Canada, France, Germany, Italy,
Japan, Switzerland, UK and USA are actively represented in WG 9, along
with international liaisons, one of which is Ada-Europe.  The proposed
amendment that creates the Ada 2005 standard has since been submitted
to formal balloting at the next ISO level, the Standards Committee SC
22, which deals with all Programming Languages. The formal ballot at SC
22 level is now well underway and is due to complete by September 1st,
2006. After approval at SC level, the proposed amendment needs to pass
a final balloting stage at the highest level of authority within ISO,
the Joint Technical Committee JTC 1, which is in charge of the whole
Information Technology sector. The final balloting stage at JTC 1 level
will commence straight after completion of the SC 22 ballot and is
expected to complete in November 2006.

All members of WG 9 and all those who collaborated in producing the
definition of the Ada 2005 standard are enthusiastic about the wealth
of innovative features that are to greatly increase the attractiveness
of the language in applications where reliability, safety, efficiency,
openness and maintainability are paramount.

"The WG 9 ballot completed even earlier than planned," said Prof.
Erhard Ploedereder, President of Ada-Europe. "This is a clear token of
the eagerness of the Ada community to see through ISO standardization
and of their full satisfaction with the technical contents of the new
standard. Ada-Europe has backed up to a very important level, both
technically and financially, the specification and formalization of the
Ada 2005 standard. Throughout the whole Ada 2005 process we have
witnessed Europe gain an increasingly prominent role, in full
collaboration with the rest of Ada community worldwide. Ada-Europe has
acted as a key facilitator of that process and we are truly proud of
the result achieved."

Ada 2005 offers a wealth of new features and enhancements in a number
of areas. The Object-Oriented Programming features have been extended
with Java-like interfaces attractively enhanced to provide safe
integration with concurrent programming. The language now also permits
to use the more conventional "object.operator" syntax, to which OOP
users have grown accustomed. Program structuring features, which were
always one of Ada's strong points, have been further enhanced to ease
the definition of mutually-dependent package specifications. Real-time
system support, where Ada has always been far ahead of other mainstream
programming languages, has been extended to additional and even
coexisting task dispatching policies including well-known Earliest
Deadline First (which is an absolute first!), execution-time clocks
along with time budget monitoring, and task termination handlers. The
standard includes full compile-time and run-time support for the
Ravenscar Profile, which is a great aid to high-integrity applications.
The predefined environment of the language has been extended with
several new capabilities including a brand-new Containers library. A
number of further enhancements were also made to increase the general
expressiveness of the language, including more flexible and yet safe
use of access values. In all, Ada 2005 is an even safer and more agile
language than its predecessors, loosing none of the efficiency that has
been a hallmark of the Ada language design.
