Subject:      Simple Date Problem

Dear

Hello.  I have a simple(?) problem.  In the data set, there are date (year)
variable. For example,

OBS     Date
1          1970
2          1971
3          1973
...          ...

I would like to extract some observation by Date.  For example, I would like
to extract observation of which date is 1971.  But unfortunately, when I
enter the command as below,

Data temp;
   Set Above;
       If Date=1970;
Run;

Then, there is no observation.  I find out why.  The date is formatted by
the date of 1960. 1.1.  For example, when I give the range like below,

Proc Print Data=Temp;
     Where 3000<=Date<=5000;
Run;

I can see observations of which date is about 1970s.  How can I treat this
variable?  Can I use the Date variable more easily?

Thank you.
