一、
在文本处理领域，字符串按特定规则分组是一种常见的操作。在 Snobol4 语言中，我们可以利用其强大的模式匹配【7】和字符串操作功能来实现这一需求。本文将详细介绍如何使用 Snobol4 语言实现字符串按字符 ASCII 码值分组的技巧。
二、Snobol4 语言简介
Snobol4 是一种高级编程语言【8】，由 Stephen C. Johnson 在 1962 年设计。它主要用于文本处理，具有简洁、易读【9】和强大的模式匹配能力。Snobol4 的语法相对简单，但功能强大，特别适合于处理字符串和文本数据。
三、字符串按 ASCII 码值分组的基本概念
在 Snobol4 中，字符串按 ASCII 码值分组意味着将字符串中的每个字符按照其 ASCII 码值进行分类。例如，可以将所有小写字母、大写字母、数字和其他字符分别分组。
四、实现字符串按 ASCII 码值分组的 Snobol4 代码
以下是一个简单的 Snobol4 程序，用于将输入字符串按 ASCII 码值分组：
```snobol
:input
input line
output
