一、
Snobol4（String-oriented and Symbolic OBject Language）是一种高级编程语言，最初于1962年由David J. Farber、Ralph E. Griswold 和 Ivan P. Polonsky 设计。它以其强大的字符串处理能力而著称，特别适合于文本处理^【6】任务。本文将重点介绍如何使用 Snobol4 的模式匹配功能来查找字符串中所有标点符号的位置。

二、Snobol4 语言简介
Snobol4 语言具有以下特点：
1. 强大的字符串处理能力；
2. 简洁的表达式^【7】和语法^【8】；
3. 丰富的模式匹配功能；
4. 高效的运行速度。

三、模式匹配基础
在 Snobol4 中，模式匹配是一种强大的文本处理工具，可以用来查找、替换和修改字符串。模式匹配的基本语法如下：

pattern [any-of] [any-of] ... [any-of] [any-of]

其中，pattern 是一个或多个字符的序列，any-of 表示匹配任意一个字符。

四、查找字符串中所有标点符号的位置
为了查找字符串中所有标点符号的位置，我们可以使用 Snobol4 的模式匹配功能。以下是一个简单的示例代码：

```
input: "Hello, World! How are you doing today?"
output: "1, 5, 7, 12, 13, 22, 24, 29, 30, 31"

:find punctuation
[',', '.', '!', '?', ':', ';', '-', '(', ')', '[', ']', '{', '}', '', '/', '', '|', '^', '&', '', '~', '`', '"', "'", ' ']
