Snobol4【1】 语言实战：半角标点【2】转换实战

Snobol4 是一种古老的编程语言，最初由Ralph E. Griswold在1962年设计。它以其简洁的语法和强大的字符串处理【3】能力而闻名。尽管Snobol4在现代编程语言中并不常见，但它在处理文本和字符串操作方面仍然有其独特的优势。本文将围绕Snobol4语言，通过一个半角标点转换的实战案例，展示Snobol4在字符串处理方面的能力。

Snobol4 简介

Snobol4是一种高级编程语言，特别适合于文本处理【4】和字符串操作。它的语法简洁，易于理解，但同时也具有一些独特的特性，如模式匹配【5】和字符串替换【6】。Snobol4的变量命名规则【7】比较宽松，可以使用字母、数字和下划线，但不能以数字开头。

半角标点转换背景

在计算机编程和文本处理中，半角标点（如英文的逗号、句号等）和全角标点【8】（如中文的逗号、句号等）是两种常见的标点符号形式。在某些情况下，我们需要将文本中的半角标点转换为全角标点，或者相反。例如，在处理中英文混合的文本时，可能需要将半角标点转换为全角标点，以便在中文环境中正确显示。

实战案例：半角标点转换

以下是一个使用Snobol4语言实现的半角标点转换程序。该程序将输入的半角标点文本转换为全角标点文本。
