求教陈老师：我的对话框为什么读不出数据？

陈老师：
　　我设计了一个计算三心拱巷道断面积的小程序，lsp原程序运行没有问题，与对话框整合后，对话框可被激活，但从中读不出数据，现将两个程序附后，烦请陈老师给诊断一下。
　　　area1:dialog{
      label="巷道断面计算";
      :row{
         :boxed_column{
                        :edit_box{label="巷道宽度　b";
                                 key="edit_b";
                                 edit_width=8;
                                 }
                        :edit_box{label="墙高　h3";
                                 key="edit_h3";
                                 edit_width=8;
                                 }
                        }
            :boxed_column{
                        :popup_list{label="支护厚度　tt";

您对于DCL控件的动作设置还不明白。例如：
应当是：(Action_Tile "edit_b" "(SetQ b $Value)")
而不是：(setq b (atof (get_tile "edit_b")))
详细规则和有关范例参见《Visual LISP程序设计——技巧与范例》第4章

对应部分这样改试试：
(setq dcl_id (load_dialog "e:/applications/dcl/area1.dcl"))
(new_dialog "area1" dcl_id)
(action_tile "accept" (strcat
"(setq b (atof (get_tile \"edit_b\")))"
"(setq h3 (atof (get_tile \"edit_h3\")))"
"(setq tt (atof (get_tile \"edit_tt\")))"
"(setq t1 (atof (get_tile \"edit_t1\")))"
(start_dialog)
(unload_dialog dcl_id);注：须加入此句
