Bernard S. Greenberg is a programmer and computer scientist, known for his work on Multics and the Lisp machine. ==Projects== In 1978, Greenberg implemented Multics Emacs〔Bernard S. Greenberg. ''Multics Emacs: The History, Design and Implementation'', http://www.multicians.org/mepap.html〕 using Multics Maclisp. The success of this effort influenced the choice of Lisp as the basis for later versions of Emacs.〔(Multics Lisp (Multics MacLisp) ) (SoftwarePreservation.org)〕〔(Jamie Zawinski's Emacs Timeline )〕 Greenberg was involved in the design of the "New Error System" at Symbolics, which in turn influenced the condition system adopted by ANSI Common Lisp.〔(Condition System, Revision #18 ) by Kent Pitman (12-Mar-88)〕 While working at Symbolics, Greenberg implemented the Lisp machine File System (LMFS).〔(Blog entry (11-Nov-2007) ) by Daniel Weinreb〕 In 1987, Greenberg and Sonya Keene authored RFC 1037. ''NFILE - a file access protocol''. In 1994, (NYCSubway.org ) released Greenberg’s NXSYS – a design environment for, and simulator of, the control signals used by the New York City Transit Authority’s signaling and control networks. The current version of NXSYS is a Microsoft Windows application that makes use of the OpenGL API to provide an interactive 3D view from the perspective of a New York subway motorman. According to (the online documentation ), the NXSYS “relay language” is a subset of Lisp that describes subway track systems and control signal pathways; the subway simulation is actually run by the Lisp program, compiled by NXSYS, from the relay language source.〔NYCSubway.org — (Subway Signals: A Complete Guide ): Bernard S. Greenberg. ''NXSYS, Signalling and Interlocking Simulator,'' http://www.nycsubway.org/wiki/NXSYS,_Signalling_and_Interlocking_Simulator#Download (Retrieved 22-Feb-2013)〕 Together with Thomas Milo, Greenberg is the author of Basis Technology's Arabic editor. It handles, among others, an improved version of the DMG (Deutsche Morgenländische Gesellschaft) transcription method, which supports reversible transcription and semi-reversible transliteration for Arabic text. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bernard Greenberg」の詳細全文を読む スポンサード リンク
