[LISP]计算单行文字+、-、*、/的程序

cenyong

　　本人前几天找到一个计算单行文字的用LISP语言编的可实现+、-、*、/的程序，加载后从命令行输入JS就行了，共享一下，代码如下：

(defun *error* (ERROR)
     (princ "error:")
     (princ "CAO ZUO ERROE")
     (PRINC "\n please try a time")
     )
(defun getss(/ SS N I NAME0 NAME X0 X1)
     (INITGET (+ 1 2 4))
     (setq ss (ssget '((0 . "TEXT"))))
     (if (= ss nil) (setq ss (ssadd)))
     (setq ssa (ssadd))
     (while (/= (setq n (sslength ss)) 0)
            (progn
            (setq i 1)
            (setq name0 (ssname ss 0))
            (setq x0 (caddr (assoc 10 (entget name0))))
            (while (< i n)
                  (progn
                  (setq name (ssname ss i))
                  (setq X1 (caddr (assoc 10 (entget name))))
                  (if (< X0 X1)
                       (progn
                       (setq name0 name)
                       (setq  X0  X1)
                  ))
                  (setq i (+ 1 i))
              ))
              (setq ssa (ssadd name0 ssa))      
              (setq ss (ssdel name0 ss))
       ))
       )
