What is the logic (rules) for adding the period ?

Is it adding after the 3rd character in case of more than 3 characters ?

then:

      data want;

       set have;

           if length(strip(ID)) > 3 then 

             ID  = catx('.', substr(ID,1,3) , substr(ID,4));

      run;

Or even:

data WANT;
  set HAVE;
  ID = catx('.', substr(ID,1,3) , substr(ID,4));
run;
