Ada 2005 Rationale - Predefined library (pt 7 of 8)

This paper describes various improvements to the predefined library in Ada 2005.

There are a number of important new core packages in Ada 2005. These include a number of packages for the manipulation of various types of containers, packages for directory operations and packages providing access to environment variables.

The entire ISO/IEC 10646:2003 character repertoire is now supported. Program text may now include other alphabets (such as Cyrillic and Greek) and wide-wide characters and strings are supported at run-time. There are also some improvements to the existing character, string and text input–output packages.

The Numerics annex now includes vector and matrix operations including those previously found in the secondary standard ISO/IEC 13813.

This is one of a number of papers concerning Ada 2005 which are being published in the Ada User Journal. An earlier version of this paper appeared in the Ada User Journal, Vol. 26, Number 4, December 2005. Other papers in this series will be found in later issues of the Journal or elsewhere on this website.
