A# . /A sharp/ 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 {abstraction}s. The compiler produces {stand-alone executable} programs, {object} libraries in {native} {operating system} formats, {portable} {bytecode} libraries, {C} and {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}, {i386}, {i286}, {Motorola 680x0}, {S 370}; several {operating system}s: {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.

A-0 . (Or A0) A language for the {UNIVAC I} or II, using {three-address code} instructions for solving mathematical problems. A-0 was the first language for which a {compiler} was developed. It was produced by {Grace Hopper}'s team at {Remington Rand} in 1952. Later internal versions were A-1, A-2, A-3, AT-3. AT-3 was released as {MATH-MATIC}. ["The A-2 Compiler System", Rem Rand, 1955]. [Sammet 1969, p. 12]. (1995-12-03)
a1 . Address 1 code. An a1 code {interpreter}, by Matthew Newhook was used to test compiler output. It requires {gcc} 2.4.2 or higher and is portable to computers with {memory segment} protection. {(ftp://ftp.cs.mun.ca/pub/a1)}. (1994-07-19)
A1 security . {Orange Book}
A20 handler . {IBM PC} memory manager software providing {HMA}. {XMM}s usually provide this functionality. Named after the 21st address line (A20), controlling the access to HMA. (1996-01-10)
A-3 . {ARITH-MATIC}
A3D . (Aureal 3-Dimensional?) A technology developed by {Aureal} that delivers sound with a three-dimensional effect through two speakers. Many modern {sound cards} and PC games now support this feature. A3D differs from the various forms of {surround sound} in that it only requires two speakers, while surround sound typically requires four or five. It is sometimes less convincing than surround sound but is supposedly better in {interactive} environments. For example, PC games in which sounds often move from one speaker to another favour A3D, while pre-recorded video favours surround sound. {Home (http://www.a3d.com/)}. (1999-01-26)
a56 . An {assembler} for the {Motorola} {DSP56000} and {DSP56001} {digital signal processors} by Quinn Jensen . Version 1.1 is available from an {alt.sources} archive or {(ftp://wuarchive.wustl.edu/)}. (1992-08-10)
AAC . {Advanced Audio Coding}
