SAS 小白请教数组下标越界问题-经管之家官网！

data datapf;
set processing;
i=1;
array d(855) d_1--d_855;
do while (d(i)>=Pbl_price or d(i)=0 or d(i)=.);
i=i+1;
end;
if i<855 then
do;
dayno=i;
pf_prc=d(i);
whtpf=1;
end;/*找到破发日*/
else whtpf=0;
drop d_1-d_855;
run;
程序是想用whtpf对数据集中上市公司是否破发做出标记，并将破发日期及破发当日价格储存在dayno, pf_prc中，想请教下版友为何程序会报错“ERROR: 数组下标越界，位置: 行 1145 列 13。”我得到的datapf数据集中只有一行观测，但各个变量得到的值是正确的。日志是这样的：
