prepare YEAR for interpolation

[podarum]

I'm trying to make YEAR (eg. 2007) as a year so I can use it in proc expand for interpolation.  doing YEAR YEAR4.; just converts it to a sas date year.. I want it to be left as 2007 as a date.

Do you want something like this?

data have;

informat date mmddyy10.;

format date mmddyy10.;

input date;

year=year(date);

cards;

12/10/2011

12/11/2010

12/10/2009

;

proc print; run;

All I have in the cards is :

cards;

2011

2010

2009

;

Do I create a mock MONTH and mock DAY .. remember I need to intrapolate.

Thanks
