What do you want the hash object to do here?
Straight IF logic is probably the best for what is shown, and there is no need to involve hash object.
A better learning of hash would be to study a book such as "Data Management Solutions Using SAS Hash Table Operations" by Paul Dorfman and Don Henderson (https://www.sas.com/store/search.ep?keyWords=HASH&action=Search) or read some of the many conference papers about HASH object (https://lexjansen.com/search/searchresults.php?q=HASH).
It's finally time to hack! Remember to visit the SAS Hacker's Hub regularly for news and updates.
Learn how use the CAT functions in SAS to join values from multiple variables into a single value.
