A♯ (pronounced: A sharp) is an object-oriented functional programming language distributed as a separable component of Version 2 of the Axiom computer algebra system. A# types and functions are first-class values and can be used freely together with an extensive library of data structures and other mathematical abstractions. A key design guideline for A# was suitability of compiling to portable and efficient machine code. It is distributed as free and open-source software under a BSD-like license.
Development of A# has now changed to the programming language Aldor.
A# has both an optimising compiler, and an intermediate code interpreter. The compiler can emit any of:
The following C compilers are supported: GNU Compiler Collection (GCC), Xlc, Oracle Developer Studio, Borland, Metaware, and MIPS C.
This article is based on material taken from A# at the Free On-line Dictionary of Computing prior to 1 November 2008 and incorporated under the "relicensing" terms of the GFDL, version 1.3 or later.
