file to a software program, be sure to handle the '?' characters
Note: Today we know the exact underlying plaintext for Exhibit 1, as deciphered using the published algorithm. The plaintext as found in Chapter 21 of "Silent Years" contains three (3) errors, probably introduced when the book was transcribed for print. The version for downloading has been corrected accordingly.
The three errors are:
Line 155 (before): OPHEVENTTHEPOPULATIONOFTHESESTATESUFORTHATPURPOSEOBSTRU
Line 155 (after): OPREVENTTHEPOPULATIONOFTHESESTATESUFORTHATPURPOSEOBSTRU
Line 164 (before): EIRSUBSTANCEZHEHASKEPTAMONGUSQINTIMESOFFEACEQSTANDINGAR

Exhibit 1, as printed in "Silent Years", had one incorrect ciphertext
character (at offset 10115, the incorrect "XZCGM" should be "ZXCGM").
The uploaded file has been corrected accordingly.|

This makes it difficult to determine what the exact
The excerpt is either 1,800 ot 1,807 characters long if one uses Byrne's convention for punctuation and paragraphs (the differing lengths depend on whether a period at the end of a paragraph is enciphered as 'Z' or 'WZ'). [Update - August 2010: today we know the plaintext is 1,800 characters long.]
The ASCII file does not contain the text at the top of page 305: "EXACT PLAIN TEXT OF ... MacARTHUR". The punctuation is also left unchanged.
