It looks like you have copied/pasted from a log to try and run it and it's including log lines. You need to download and compile the macro first, then call %cem(). For example, if you download it and save it to the C: drive:

%include "C:\macro_cem_updated_new_feb17.sas";

%cem(<arguments go here>);
