阿木博主一句话概括：PL/I语言中随机文件的定位与访问技术解析

阿木博主为你简单介绍：
本文旨在深入探讨PL/I语言中随机文件的定位与访问技术。通过分析PL/I语言的特点，结合实际代码示例，详细阐述了随机文件的创建、定位、读取、写入和关闭等操作，为PL/I程序员提供实用的技术指导。

一、

PL/I（Programming Language One）是一种高级程序设计语言，具有丰富的数据类型和强大的数据处理能力。在数据处理领域，随机文件是一种常见的文件类型，它允许程序以任意顺序访问文件中的记录。本文将围绕PL/I语言中随机文件的定位与访问展开讨论。

二、PL/I语言的特点

1. 强大的数据类型：PL/I支持多种数据类型，如整数、浮点数、字符等，便于处理各种数据。

2. 高效的文件处理：PL/I提供了丰富的文件处理功能，包括顺序文件和随机文件。

3. 强大的数据处理能力：PL/I支持多种数据处理操作，如排序、合并、筛选等。

4. 良好的兼容性：PL/I具有良好的兼容性，可以与多种操作系统和数据库系统协同工作。

三、随机文件的创建

在PL/I中，创建随机文件需要使用CREATE语句。以下是一个创建随机文件的示例代码：

```pl/i
