通用函数揭密与改进
通用函数是以往程序的提炼和总结，使新编程序简洁可读。以下函数仅供参考，请大家批评指正，能否更高效简洁？任何高见均会被采纳！
PHP代码:
目录：
1、cmdla--序列 位于程序的开始和结束，用于存储和恢复用户的系统变量
2、sub_upd更改图元DXF组码以修改实体属性
3、xyp-Sort-Text文本排序
4、xyp-Sort选择集排序
5、xyp-get-DXFDxf组码
6、SETBL比例设置
7、xyp-get-tblnext获得特定符号表的列表
8、xyp-DelSame删除表中的重复元素
9、xyp-Text定点写字
10、U系列函数
11、xyp-get-MinMaxPoint指定对象最小外接矩形的九点坐标
12、xyp-get-RightPoint两点中点之正方向点
13、xyp-ZB坐标标注函数
14、XYP-GET-COLOR取得物体的颜色（含随层）

实例1 : 改圆半径为500
(sub_upd (car(entsel"\n选择圆 : ")) 40 500)
