建立一根锚索的命令流如下：
sel cable id=1 beg -30 56.912 14.912 end -30 45.628 45.915 nseg 16
sel cable id=1 prop emod 20e9 ytension 310e3 xcarea 0.0004906 gr_coh 1 gr_k 1 gr_per 0.0785 ran cid 1 11
sel cable id=1 prop emod 2e9 ytension 310e3 xcarea 0.0004906 gr_coh 3.2e5 gr_k 3e7 ran cid 12 16
sel delete link range cid 11 12
sel link cid 1500 12 target node tg 11
命令输入后出现下图所示错误，请高人指教如何处理：
