建構一個用於FORTRAN的程式分析器

Abstract

分析和維護現有的軟體佔了寫程式資源的絕大部分. 根據推測, 在未來將 會花費更多比例的時間在程式的分析以及維護上. 本論文使用靜態分析去 評估FORTRAN程式. 這個分析器提出一些品質因數(Quality factors),用 以藉此評估FORTRAN程式的特性. 應用統計學的方法, 分析器根據這些品 質因數得到測量數據, 由這些測量數據推測軟體可再利用的程度. 為了達 到程式碼的再利用, 這個分析器還將FORTRAN 77的程式碼轉成FORTRAN 90的形式. Most of programming resources are allocated to analyzing and maintainingexisting software. It is estimated that these activities will consume aneven larger portion of software life cycle resources in the future. Thisthesis apply static analysis to evalute FORTRAN programs. The analyzeralso intorduces some quality factors for program evaluation. According tothese quality factors, the analyzer applies statistics to metrics; itcollects metrics data from different project to indicate reusability. Tohelp code reusability, the analyzer also performs a code translation fromFORTRAN 77 to FORTRAN 90.
