So far so good, but then with a few whacks of the Page Down key Randy’s looking at endless staggered grids of random letters (some kind of predigital method for solving ciphers) which the author would not have put into the document if they did not convey some kind of useful lesson to the reader. Randy is miserably aware that until he has learned to read through these grids he will not even be up to the level of competence of a World War II novice cryptanalyst. The sample messages used are like ONE PLANE REPORTED LOST AT SEA AND TROOPS HAVING DIFFICULTY MAINTAINING CONNECTION WITH FORTY FIFTH INFANTRY STOP which Randy finds kind of hokey until he remembers that the book was written by people who probably didn’t know what "hokey" meant, who lived in some radically different pre-hokiness era where planes really did get lost at sea and the people in those planes never came back to see their families and in which people who even raised the issue of hokeyness in conversation were likely to end up pitied or shunned or maybe even psychoanalyzed.
