Paterson (poem) caught Williams' attention for its use, with a technical skill that seemed to rival Pound's in "The Cantos", of such diverse and seemingly prosaic materials as notes from a congressional investigation, an X-ray report and a physician's testimony on cross-examination. He wrote to fellow poet Louis Zukofsky, "I've begun to think about poetic form again.

In 1944, Williams read a poem by Byron Vazakas in "Partisan Review" that would help lead him to solutions in form and
LL parser empty stack. The states and the transition function are not explicitly given; they are specified (generated) using a more convenient "parse table" instead. The table provides the following mapping: If the parser cannot perform a valid transition, the input is rejected (empty cells). To make the table more compact, only the non-terminal rows are commonly displayed, since the action is the same for terminals. To explain an LL(1) parser's workings we will consider the following small LL(1) grammar: and parse the following input: We construct a parsing table for this grammar by expanding all the terminals by column and all
