可以了,谢谢! data cashind4; set cashind3; a0new=a0*1; run;
我原来使用 a0=a0*1的时候, data cashind4; set cashind3; a0=a0*1; run; 然后就出现这样,转换不过来,现在用新变量就好了 NOTE: Character values have been converted to numeric values at the places given by: (Line):(Column). 46:4 NOTE: Numeric values have been converted to character values at the places given by: (Line):(Column). 46:6
