Technical Group Reaches Consensus
and Moves Language Amendment to Next Milestone
SALT LATE CITY, UT [May 2, 2006]—
Today at the Systems & Software
, the Ada Resource Association announced the accomplishment of a major milestone
in the development of the new Ada ISO standard. ISO’s Ada Working Group (WG 9) has unanimously
accepted the proposed amendment to the language and has forwarded it to the parent organization for
an official ballot. Formal approval by ISO is expected some time later this year.
The new amendment to the language, commonly referred to as Ada 2005, culminates a collaborative international
effort to enhance the 1995 version of the Ada language. The effort was sponsored
in part by the Ada Resource Association
, which helped support the work of the project editor, Mr. Randall Brukardt
"Gaining WG 9 approval for the amendment to the language is a key step," said Mr. James Moore,
Convener of WG 9. "The new features draw on programming language design and user experience
over the past ten years, and they should serve to increase Ada's attractiveness in applications where
reliability, safety, efficiency, and maintainability are demanded."
"Ada 2005 is a breakthrough in language technology," added Dr. Ben Brosgol
, President of the
Ada Resource Association. "It has advanced the state of the art in language design while preserving
Ada's long-standing support for sound software engineering. WG 9 is to be congratulated for bringing
this effort to fruition with a strong consensus on the features being added."
Ada 2005 offers significant enhancements in several areas. Improvements in the language's Object-Oriented
Programming features include the addition of Java-like interfaces and traditional "object.operation" syntax.
More flexible program structuring allows mutually dependent package specifications and makes it easier
to interface with languages such as Java. Real-time system support includes additional task dispatching
policies such as Earliest Deadline First, execution-time clocks, and handlers for task termination.
The concurrency and object-oriented features are successfully unified through a new interface feature
that allows implementation through either a sequential or concurrent type.
Support for safety and
security is enhanced with the inclusion of the Ravenscar Profile (a tasking subset that is amenable
to safety certification), syntax that avoids some common Object-Oriented Programming errors with
inheritance, and a mechanism for defining language profiles. Other enhancements increase the language's
general expressiveness, for example by allowing nested subprograms to be passed as run-time parameters,
and by extending the predefined environment with new functionality, such as a Containers library.
