It supports many procedural programming constructs and convenience features such as minimal structural overhead that is , " classless " coding and little or no need to declare variable types 它支持许多过程性的编程结构以及方便的特性，例如最小的结构性开支（也就是说，可以编写“没有类”的代码） ，而且很少或几乎不需要声明变量类型。
First , since this is the scheme language , the types are bound to the values themselves , not the variable names , so there is no worry at all about the variable type problems that occurred in the c version 首先，由于这个宏采用的是scheme语言，因此类型都已经被绑定到值本身上面了，而不是绑定到变量名上面，因此根本不用担心会出现c版本中那种变量类型的问题。
Visual basic now has the same variable types , arrays , user - defined types , classes , and interfaces as visual c and any other language that targets the common language runtime ; however , some features such as fixed - length strings had to be removed from the language 现在， visual basic具有同visual c + +以及针对公共语言运行库的其他任何语言相同的变量类型、数组、用户定义的类型、类和接口；然而，不得不将某些功能（如定长串）从该语言中移除。
