Object Pascal 参考手册 （Ver 0.1） ezdelphi@hotmail.com Overview - 1 - Overview（概述） Using object pascal（使用 object pascal） Object Pascal 是一种高级编译语言，具有强类型（对数据类型的检查非常严格）特性，支持结构化 严格）特性，支持结构化 和面向对象编程。它的优点包括代码的易读性、快速编译，以及支持多个单元文件从而实现模块化编程。 Object Pascal 具有一些特性以支持 Borland 组件框架和 RAD（快速应用程序开发）环境。在很大程 度上，本语言参考的说明和示例假定你使用 Borland 公司的开发工具，如 Delphi 和 Kylix。 绝大多数使用 Borland 开发工具的开发者是在 具在程序的组织上还有一些限制，严格说来，这不是 Object Pascal 语言规范的一部分。比如，Borland 开发工具遵循某些文件和程序的命名约定，若你在 IDE 以外编写代码并使用命令行来编译，你可以避开 这些限制。 这些帮助主题假设你在 IDE 环境下工作，并且使用 VCL（可视化组件库）和/或 CLX（跨平台组件 库）创建应用程序。但有时候，Borland 一些特定的规则和 Object Pascal 的通用规则并不相同。
