人和计算机交流信息使用的语言称为计算机语言或称程序设计语言。计算机语言通常分为机器语言、汇编语言和高级语言三类。如果要在计算机上运行高级语言程序就必须配备程序语言翻译程序（下简称翻译程序）。翻译程序本身是一组程序，不同的高级语言都有相应的翻译程序。翻译的方法有两种：
The language used for communication between humans and computers is called computer language or programming language. Computer languages are usually divided into three categories: machine languages, assembly languages, and high-level languages. If you want to run high-level language programs on a computer, you must be equipped with a program language translation program (hereinafter referred to as a translation program). The translation program itself is a set of programs, and different high-level languages have corresponding translation programs. There are two methods of translation:
一种称为“解释”。早期的BASIC源程序的执行都采用这种方式。它调用机器配备的BASIC“解释程序”，在运行BASIC源程序时，逐条把BASIC的源程序语句进行解释和执行，它不保留目标程序代码，即不产生可执行文件。这种方式速度较慢，每次运行都要经过“解释”，边解释边执行。
One type is called "explanation". Early BASIC source programs were executed in this way. It calls the BASIC interpreter provided by the machine, and when running the BASIC source program, it interprets and executes the BASIC source program statements one by one. It does not retain the target program code, that is, it does not generate an executable file. This method is relatively slow and requires "explanation" every time it runs, executing while explaining.
