Work here included real time control firmware , graphics and communications software , and a generic macro language .

工作包括实控软件，制图，交流软件以及通用宏语言。

I can see two main explanations , one micro , the other macro .

我可以想到两种主要解释，一种是微观的，另一种是宏观的。

If you 're not convinced yet , this might help . You can implement a macro system in 30 lines of lisp .

如果你还没被说服，以下这点将有所帮助，你可以用30行lisp代码实现一个宏系统。

Together with clojure 's dynamic typing and unchecked exceptions , this macro makes the clojure code not only more reusable , but also more readable .

和clojure的动态输入、未检查的异常一起，宏不仅令clojure代码重用性增加，而且更加易读。

When it hits one , it passes the program source as data to your macro , and you can do whatever you want with it .

当编译器找到一个宏调用，把程序源码当数据传递给你的宏，你可以对这段代码进行任何你想要的处理。
