SAS代码如下:
data one;
x=5;
y=input(x,best.);
;
run;
以上运行后会在log里提示:

NOTE: Numeric values have been converted to character
      values at the places given by: (Line):(Column).
      341:9
如果重复提交这个代码,log会提示
NOTE: Numeric values have been converted to character
      values at the places given by: (Line):(Column).
      345:9
如果继续重复运行这段代码,每次line都是累加的.

请问如何设置options参数使line初始化??
