In this paper , the main features of structured FORTRAN language are discussed. Showing that, how a prepocessor (translater) from structured FORTRAN to FORTRAN is implementated at TQ-16 computer. 本文讨论结构FORTRAN语言的特点并给出TQ—16机结构 FORTRAN语言的实现方法。 This paper presents a method for checking syntactic errors of ALGOL 60 source programs. This method consists in reducing the handling of recursivity of syntactic definitions to that of the structures without boldface type words and the combinations of the connective boldface type words of structured statements. It is simple and easy, and has been implemented on the computer PALLAS in Nanking University (i. e. version 1555 of PALLAS ALGOL 60 Checker). As a result of applying this Checker to so many user... This paper presents a method for checking syntactic errors of ALGOL 60 source programs. This method consists in reducing the handling of recursivity of syntactic definitions to that of the structures without boldface type words and the combinations of the connective boldface type words of structured statements. It is simple and easy, and has been implemented on the computer PALLAS in Nanking University (i. e. version 1555 of PALLAS ALGOL 60 Checker). As a result of applying this Checker to so many user programs, it indicates that almost all errors of a source program in compile-time can bedetected. In this paper the features of version 1555 are described briefly. A comparison with the original version is given. This paper also points out the drawbacks of this version and the way to improve it. 本文介绍检查 ALGOL 60 源程序语法错误的一种方法。该方法在于把处理语法定义的递归性问题约化为处理无粗体字结构及构造型语句连接粗体字的组合问题。它平易简捷,已在南京大学PALLAS计算机上实现(即1555 ALGOL 60错误检查程序)。对数十个用户程序的应用表明:它一次可查出几乎所有的编译时刻错误。文中简略叙述了1555版本的特点,并就实例与原有编译系统进行对照。本文也指出了这版本的不足之处与改进方向。 This paper presents a method for checking syntactic errors of ALGOL 60 source programs.
