如果我这样说我的规则行得通
RULE 1 : IF distance_obs IS positive AND haut_ob IS negative AND haut_cib IS positive THEN x1 IS GR1 , y1 IS EZ11 ;
但是当我再添加一个输出时，像这样
RULE 1 : IF distance_obs IS positive AND haut_ob IS negative AND haut_cib IS positive THEN x1 IS GR1 , y1 IS EZ11 , z1 IS UP1 ;
输入''不匹配，期望SEMICOLON
请提供任何帮助??
