标题: 请教SAS ADVANCE 题目2 [打印本页] 作者: shiyiming 时间: 2010-7-26 16:41 标题: 请教SAS ADVANCE 题目2 The following SAS program is submitted:
data WORK.TEMP;
length A B 3 X;
infile RAWDATA;
input A B X;
run;
What is the length of variable A?
A.
3
B.
8
C.
WORK.TEMP is not created - X has an invalid length.
D.
Unknown.
通过运行SAS， 发现提示为X的长度不对，出错。 应该赋予一数值，
但是有答案提示为选A。
故有疑问！ 拟向高手请教！谢谢！作者: shiyiming 时间: 2010-7-26 17:04 标题: Re: 请教SAS ADVANCE 题目2 我觉的是这意思
