看以下程序： ------------------------------------------------------ 点1 =特征/接触/矢量点,直角坐标 理论值/<39.688,78.662,14.224>,<0.170838,-0.1945877,0.9658934> 实际值/<39.688,78.662,14.224>,<0.170838,-0.1945877,0.9658934> 目标值/<39.688,78.662,14.224>,<0.170838,-0.1945877,0.9658934> 显示高级测量选项=否 显示相关参数=否 赋值/V1 = "点" 赋值/V2 = 1 赋值/V3 = ".TZ" 赋值/V4 = V1+V2+V3 赋值/V5 = 点1.TZ -------------------------------------------------------------------------------- 程序中，为什么赋值V4不行呢？而V5就等于14.224 求高人解答！谢谢！！！
