Then, when the program was all figured out on paper, they'd painstakingly expand and translate it into binary machine code by hand, using things like opcode tables.

然后，当程序全部在纸上弄清楚时，他们会使用操作码表之类的东西，煞费苦心地手动将其扩展并翻译成二进制机器代码。

This is a specialized program that transforms " source" code written in a programming language into a low-level language, like assembly or the binary " machine code" that the CPU can directly process.

这是一个专门的程序，可以将用编程语言编写的“源”代码转换为低级语言，如汇编或 CPU 可以直接处理的二进制“机器代码”。
