This article needs to be cleaned up. Some of the language, such as "toing and froing" is simply awkward. The extensive use of parentheticals, especially in the 'Decryption' section, further degrades readability. 24.107.177.15 11:51, 1 November 2006 (UTC)

I thought that Magic applied to All Japanese high-grade sigint (or All Japanese sigint), not just PURPLE. See Harry Hinsley, David Kahn, & Alan Stripp: ‘’Codebreaking in the Far East’’ page 152 (1989, 1995 Oxford pb) ISBN 0-19-280386-7 Hugo999 10:58, 5 February 2007 (UTC)

According to Mr. Gordon Prange's tome on the Japanese attack on Pearl Harbour ('At Dawn We Slept'), Magic did indeed refer to all Japanese diplomatic codes derived from Purple. These included Red, Purple and the J codes. Note that by the time of the attack the navy codes hadn't been broken yet, so these are stricly diplomatic in nature (although some information sent to the Honolulu contains purely military instructions). -- Ishikawa Minoru 17:16, 3 October 2007 (UTC)

[edit] Information carried in PURPLE traffic

What is underneath the first heading does not seem to correlate with the title and/or is out of place in this article and would probably be better placed in an article regarding the attack on Pearl Harbor or an article regarding the post attack hearings.

Also I removed the last sentence "Magic was the Japanese Code, after Purple was figured out by the United States." this appears to be outright wrong if the rest of the article is correct. ASA-IRULE 20:58, 18 September 2007 (UTC)
