It calculates the value of TEST_x (defined 100) plus 1 and then converts the whole thing to a string or something. However, I don't see any usefulness in this either. If Gamer_Z can provide me with a real world example to demonstrate its true usefulness (i.e. something that can't be done with the current preprocessor directives), I might come back on my opinion.
