How to separate those IDs into two parts

[superbug]

I have an ID variable $10.. In this variable, some candidates' ID is 9 numbers, while some other candidates' ID is 7 numbers.  Picture below is an example. How can I separate the candidates into two groups, i.e. one group with 9 number ID, and the other group with 7 number ID. Thanks much for the help!

For example, the following code will store the length of the id in the group variable, allowing you to group them.

data want;
  set have;
  group=length(id);
end;
