体验COBOL语言

最近由于新冠肺炎导致COBOL程序员短缺的报道时有发生，于是对这门超级古老的语言感到好奇。经过一番搜索，居然发现archlinux上就有一个COBOL语言的编译器叫 gnucobol.

在它的官网上有许多资料，包括COBOL编程指南和 gnucobol本身的使用手册. 有兴趣的同学可以试试。

下面是一个COBOL版的Hello world

000100* HELLO.COB GnuCOBOL example
000200 IDENTIFICATION DIVISION.
000300 PROGRAM-ID. hello.
000400 PROCEDURE DIVISION.
000500     DISPLAY "Hello, world!".
000600     STOP RUN.

前六位是标号， * 开头的行为注释行。给我的感觉是跟AS400上的RPG有点像。
