A sharp

A# (A sharp) is a separable component of Version 2 of the AXIOM*[?] computer algebra system. It provides a programming language with an optimising compiler[?], an intermediate code interpreter, and a library of data structures and mathematical abstractions[?]. The compiler produces optionally stand-alone executable programs[?], object libraries[?] in native operating system formats, portable bytecode libraries, C or Lisp source code.

The A# programming language has support for object-oriented and functional programming styles. Both types and functions are first class values that can be manipulated with a range of flexible and composable primitives and user programs. The A# language design places particular emphasis on compilation for efficient machine code and portability.

Ports have been made to various 16, 32, and 64 bit architectures: RS/6000, SPARC, DEC Alpha, IA-32, Intel 286, Motorola 680x0, S 370[?]; several operating systems: Linux, AIX, SunOS, HP/UX[?], Next, Mach and other Unix systems, OS/2, DOS, Microsoft Windows, VMS and CMS; C compilers: Xlc[?], gcc, Sun[?], Borland, Metaware[?] and MIPS C[?].
