To enable verbose messages, have the statement"enable verbose";as the first line of your program. This also causes the program to be run by the interpreter. There are two main kinds of error messages: those that occur at runtime and those that occur at parse time. The first can be foun...
从这个角度来说,可以把 Lisp 程序看成是完全由"函数调用"这个单一的语法结构构成。 Lisp 里面没有为了算术表达式、或者逻辑表达式、或者语言的关键字,比如 IF 和 THEN,来准备特别的语法结构。所有的语言元素在 Lisp 里面都是按照这个简单一致的语法结构来安排。不过和一般的程序语言里面不同的是下面这个表达式。 ((...
、、、 考虑一个超类: class superclass { public void fun() {...} } 它是子类: class subclass extends superclass { public void fun(){...} public static void main() { superclass sup1=new superclass(); sup1.fun()//statement 1 superclass sup2=new subclass(); sup2. 浏览0提问于2018...
(A "test" Scheme file is a simple syntax extension over "plain" Scheme: statement => expected-output.)However, just like with the interpreter, the invocation is quite simple:vonuvoli-scheme-tester /.../script.sst vonuvoli-scheme-bencher /.../script.sst ...

Scheme的简约性使它成为具备同级别功能的编程语言中最易于实现的语言[15]。Scheme的很多结构源于λ演算,例如let可以写作创造并调用一个匿名函数: (define-syntaxlet(syntax-rules()((let((var expr)...)body ...)((lambda(var ...)body ...)expr ...))) 换...
