部的细分:divisionssectionsparagraphssentencesstatements 编程格式: 1-6序列列:为“标号区”(sequence area)。可以填写6个数字。标号由程序编写者自定,标号应按由小到大的顺序,但不一定连续。标号区内可以写标号也可以不写标号(标号区空白)。标号对源程序的执行结果没有任何影响。在程序编译时是按程序书写的顺讯进...
The COBOL program has a hierarchical structure that comprises divisions, sections, paragraphs, sentences, verbs and character strings. The divisional nature of a COBOL system (which comprises four divisions) enables a distinct separation of concerns within COBOL programs. COBOL divisions are as follows...

A COBOL program is made up of four Divisions: 1. The IDENTIFICATION DIVISION. This must contain the program's name — as follows: PROGRAM-ID. name 2. The ENVIRONMENT DIVISION. If the program uses peripheral devices (e.g. disk, tape, printer) — details will be shown here. Otherwise, ...
