The second IF is not necessary, as that (I assume default) constellation is handled by @japelin 's solution. Just add your first IF to the code that @japelin provided, and handle similar extraordinary situations the same way.
Setting everything manually is a human task, not suited for programming.
how about this.
data want;
set have;
length userid $20;
userid=substr(scan(username,1),1,1)||scan(username,2);
run;
