一、
日期时间格式化是编程中常见的需求，特别是在处理日志、用户界面显示和数据处理时。Snobol4 语言虽然不如现代编程语言那样广泛使用，但其强大的字符串处理能力使其在处理日期时间格式化任务时具有独特的优势。本文将展示如何使用 Snobol4 语言实现一个简单的日期时间格式化函数。
二、Snobol4 语言简介
Snobol4 是一种高级编程语言，由David J. Farber和Ralph E. Griswold于1962年设计。它以其简洁的表达方式和强大的字符串处理能力而闻名。Snobol4 的语法简单，易于学习，但同时也存在一些限制。
三、日期时间格式化函数的设计
为了实现日期时间格式化函数，我们需要考虑以下几个步骤：
1. 解析日期时间字符串
2. 验证日期时间字符串的有效性
3. 格式化日期时间字符串
4. 输出【7】格式化后的日期时间字符串
下面是一个简单的 Snobol4 代码示例，实现了上述功能：
```snobol
:parse-date【8】
'YYYY-MM-DD【10】' !date
date 4 4 !year【11】
date 6 2 !month【12】
date 9 2 !day【13】
