MIX的模拟器： MIX是《计算机程序设计艺术》(TAOCP)的作者高德纳(Donald.E.Knuth)在TAOCP中描述算法时使用的一种假想的机器，所以书中的汇编代码无法在任何一个机器上运行，附件中的程序可以让以MIXAL汇编语言写成的算法在Windows平台上汇编并且可以单步跟踪运行。详细情况参看其中的MIXBuilder.doc文件。 -MIX simulator : MIX "Art of Computer Programming" (TAOCP), the author of Donald Knuth (Donald.E.Knuth) TAOCP algorithm describes the use of an imaginary machine, a compilation of the book in any code not run on a machine, the Annex procedures to allow MIXAL compilation algorithm written in the language in the Windows platform compilation and can single-step tracking operation. See details of the MIXBuilder.doc document.
