1、大连理工大学课程大作业课程名称：COBOL商业编程技术学院（系）：软件学院专业：大型机方向班级：学号：学生姓名： 2011年 4月 25日一、实验内容(1) 实验背景：假设有一公司要实现系统更新，将从开始至2011年一季度的数据备份到一个文件（数据集RYO.COBOL.RPT3000.FOLD）中，将第二季的数据保存在另一文件（数据集RYO.COBOL.RPT3000.FREC）中，要系统更新完成，要将两数据整合，并且第二季中的数据包括新的分公司的成立，原分公司的倒闭，原分公司数据更新。(2) 实验要求：现要实现判断第二季度中的数据集中内容判断是否合法，将不合法的输出到错

2、误文件（数据集RYO.COBOL.RPT3000.FERR）中，将倒闭（关闭）的分公司数据输出到（数据集RYO.COBOL.RPT3000.FCLO）中，将新的整合后的数据保存到（数据集RYO.COBOL.RPT3000.FNEW），并最终打印成报表输出到（数据集RYO.COBOL.RPT3000Z.OUTPUT01）中。二：实验目的1）了解COBOL语言格式，数据类型和基本运算，能熟练掌握编写COBOL 程序的技能2）熟练掌握EVALUATE语句和PERFORM UNTIL语句等COBOL流程控制3）熟练掌握对数据的排序和合并操作（SORT&MERGE）及对文件的操作4）掌握表的基本

3、用法和优点5）熟练掌握子程序调用方法和具体实现原理6）能正确编写JCL语言运行COBOL程序三：实验核心内容实验代码分类如下：（1）主程序代码（2）子程序代码（3）编译程序代码（4）运行程序代码（5）输入数据1：RYO.COBOL.RPT3000.FOLD（6）输入数据2：RYO.COBOL.RPT3000.FREC（6）输出数据1：RYO.COBOL.RPT3000.FERR，RYO.COBOL.RPT3000.FCLO（7）输出数据2：RYO.COBOL.RPT3000.FNEW（8）最终生成报表：RYO.COBOL.RPT3000Z.OUTPUT01主程序结构图：
