编起来是什么样子的?是不是很难的?能不能给我一个例子?
能把具体的代码写出来吗?谢谢了(dypsoft前一部分的代码这么没层次感的?是不是LISP就是这样的?我真的连一行LISP也没见过的啊.谢谢了)
我还是喜欢LISP，说过时？呵呵，那你问问天正软体是用什麽开发出来的。其实也挺简单的，举个例子的话，因为我是做建筑设计的，自已写了个Z坐标一次归0的LISP：(vmon) (defun c:zz (/ wholesel count treatcount chcount ent curent segcurent entlist segentlist etflag dfetflag input ) (command "_.undo" "_begin") (setq old_err *error* *error* zz_err ) (princ " ***********Z坐标值归零程序***********作者 燕鹏动力******" ) (setvar "cmdecho" 0) (setq wholesel (ssget '((-4 .
