STOP RUN. This is because we want to define these as things we can do but we don’t actually want to run them in the procedure division so we put them in paragraphs outside the procedure division. I think what happens is it sets a pointer to the beginning and as you push things into the final string it pushes the pointer down several locations which are then stored as a count.
