"Do, lines 110-160 provide the data for building the numbers formed by lines 221-237?"
Yes, 110-160 specify to build the next digit as a 2,3,5 or 7. It recurses (via the called subroutine), so that 221-237 then recognizes if all 9 digits have been built, then forms and tests the 3-digit numbers from the 9 chosen digits arrangements.
