6.程序由表达式(expression)组成。Lisp程序是一些表达式区块的集合,每个表达式都返回一个值。这与Fortran和大多数后来的语言都截然不同,它们的程序由表达式和语句(statement)组成。 区分表达式和语句,在Fortran I中是很自然的,因为它不支持语句嵌套。所以,如果你需要用数学式子计算一个值,那就只有用表达式返回这个值,没...

I either use one package for my entire program, or I break it into just a couple of main packages. I don’t try for a finer grained approched. The package system wasn’t really designed for a fine-grained appoach. Screwing up your packages can easily make your system unusable. If ...
xxx((zeropx)1)(t(*x(factorial(-x1))); call factorial with a positive number(write(factorial5)); terminate printing(terpri); call factorial with a negative number(write(factorial-1)) Output When you execute the code, it returns the following result − 120 ...
(where :title "Give Us a Break" :ripped t) 产生的变量将包含下面的list。 (:title "Give Us a Break" :ripped t) 这个list被传递到make-comparisons-list中,它返回包含比较表达式的list。可以使用函数MACROEXPAND-1来查看将产生什么样的调用。如果传递给MACROEXPAND-1的form是macro,它将使用适当的参数调用...
