A set of SAS assignment statements as illustrated below will work:

IF THEN ;
ELSE IF THEN ;
ELSE ;

Explore using SAS literal strings expressed as DATE values for your defined as explained in your post. The literal must be surrounded in either single- or double-quotes suffixed with a "D" character.

You have a wealth of SAS documentation and supplemental technical / conference papers available at the SAS support http://support.sas.com/ website using its SEARCH facility or with a GOOGLE search.
