It's not really clear what you are trying to do. Actionf can only have one value so you will only get one value for action. If you want to append characters use double vertical bars -- something like (untested):

Data _null_; length allaction $ 16; actiona = 'drug'; actionb = 'none'; allaction = actiona||actionb; run;
