一、
字符串排序是计算机科学中常见的问题，广泛应用于数据排序【6】、文件处理等领域。Snobol4语言作为一种具有强大字符串处理能力的编程语言，提供了丰富的模式匹配功能，使得字符串排序变得简单而高效。本文将围绕Snobol4语言，探讨基于模式的字符串排序技巧。

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。它以其强大的字符串处理能力和模式匹配功能而闻名。Snobol4语言的特点如下：

1. 强大的字符串处理能力：Snobol4提供了丰富的字符串操作函数，如字符串连接、子串提取、字符串替换等。
2. 模式匹配：Snobol4支持强大的模式匹配功能，可以方便地匹配字符串中的特定模式。
3. 简洁的表达式：Snobol4的表达式简洁明了，易于理解和编写。

三、基于模式的字符串排序技巧
基于模式的字符串排序技巧主要利用Snobol4的强大模式匹配功能，通过定义特定的模式来比较字符串，从而实现排序。以下是一个简单的示例：

```snobol
sort: (list) -> (list)
local: (list) -> (list)
if (list) = (nil) then
(nil)
else
local: (list) -> (list)
if (list) = (nil) then
(nil)
else
(list) -> (list)
if (list) = (nil) then
(nil)
else
(list) -> (list)
if (list) = (nil) then
(nil)
else
(list) -> (list)
if (list) = (nil) then
(nil)
else
(list) -> (list)
