对COBOL的最新重大更改 [英] Most recent breaking changes to COBOL

问题描述

过去一年中，由于Python v2-> v3和R v3-> v4的更改，我花了一些时间来处理代码更改.对于某些仍在使用的较旧的语言，我感到好奇.

I've spent some time in the past year dealing with changes to my code due to Python v2->v3 and R v3->v4 changes. It got me curious as to some of the older languages that are still in use.

我知道COBOL仍然偶尔会看到更新和功能升级.我认为它们的关键任务性质使这些更改更小并且更向后兼容，但是我真的不知道，也无法通过网络搜索找到它.

I know COBOL still sees occasional updates and functionality upgrades. I would assume that their mission-critical nature makes those changes smaller and more backward-compatible, but I don't really know and couldn't find it with a web search.

对COBOL的最后一次更改是什么，什么时候发生，与Python 2-> 3更改的大致顺序相同?

What and when were the last changes to COBOL that was on the same rough order as the Python 2->3 changes?

添加了54个保留字，如果不按照2002年标准使用这些保留字将导致语法错误.

Added 54 reserved words that would cause syntax errors if not used in conformance with the 2002 standard.

添加了FLAG-85指令以标识10种情况，其中相同的语法可能会产生与1985年标准不同的结果.
