It reads in a program written in an Assembly Language and converts it to native machine code.

它读入用汇编语言编写的程序并将其转换为本地机器代码。

To do this, they needed to write a program that converted BASIC instructions into native machine code, what’s called an interpreter.

为此，他们需要编写一个程序，将 BASIC 指令转换为本地机器代码，即所谓的解释器。
