Section 5.9.4 describes an error recovery method that relies on dynamically constructed sets of Follow symbols. Compare these sets with the Follow information computed for full LL(1) in Exercise 25.

Exercise 25

Section 5.9.3 contains an example where the production A→ λ is applied using an invalid look ahead token. With Follow sets computed globally for a given grammar, the style of LL(1) parsing described in this chapter is known as strong LL(1). A full LL(1) parser applies a production only if the next input token is valid. Given an algorithm for constructing full LL(1) parse tables.
