It tackled problems of crucial importance whose general solution was an important research focus in compiler technology for several decades. Many classical techniques for compiler analysis and optimization can trace their origins and inspiration to the Fortran I compiler.

  • 注意:通常人们会认为这一语句对应于IBM 704上的一个三态分支指令。但事实并非如此,704的分支指令只包含了一个目标地址(例如,TZE - 转换AC为零,TNZ - 转换AC为非零,TPL - 转换AC为加,TMI - 转换AC为减)。机器(以及它的后继者如700/7000系列英语IBM 700/7000 series#Later scientific architecture (704/709/7090/7094))确实有一个三态跳转指令(CAS - 比较AC与存储),那可能是这一说法的最初起源,但是用这一指令来执行IF的话,会消耗4个指令词,需要把常数零放入存储中,然后执行三个机器循环,而如果使用转换指令来实现IF的话,只需要1到3个指令词就够了,不需要将常数存入存储,只需要1到3个机器循环来执行。一个优化的编译器如FORTRAN最有可能采用的是更精简的和通常来说更快的转换指令,而不是比较指令(使用指换指令同时也允许FREQUENCY语句来优化IF,而如果使用比较指令的话则无法实现)。同时,比较指令还将-0和+0认为是不同的值,而转换零和转换非零语句将它们视为相同的值。
