标题: SAS 帮助里例子的运行问题
[color=#0000FF:2s03nbrs]我输入了一个SAS Help里面的例子如下：[/color:2s03nbrs]
data projects;
options nodate pageno=1 linesize=80 pagesize=60;
input Projid startdate date9. enddate date9.;
Duration=enddate-startdate;
datalines;
398 17oct1997 02nov1997
942 22jan1998 10mar1998
167 15dec1999 15feb2000
250 04jan2001 11jan2001
;

proc print data=projects;
format startdate enddate date9.;
title 'Days Between Project Start and Project End';
run;

[color=#0000FF:2s03nbrs]但是output里所有的enddate 的年份都和输入的不符，如下：[/color:2s03nbrs]

02nov2001
10mar2001
15feb2002
11jan2002

[color=#0000FF:2s03nbrs]实在是想不通问什么会这样
请大家帮忙看看。

谢谢！[/color:2s03nbrs]
