Chapter 9

The JIS Browser

The JIS Browser lets you view all the characters in the JIS (Japanese) character set. Each Japanese character is identified by a 4-digit hexadecimal number. The JIS Browser screen divides the JIS character set into 94 pages of 94 characters each. The pages number is given by the high byte (first two digits) of the JIS code and ranges from 21 hexadecimal to 7E hexadecimal. Because of the limited screen size of the Palm device, each page is subdivided into 4 "screens", each of which can display up to 24 characters.

The navigation buttons at the bottom of the JIS Browser screen let you move around the JIS character set:

-scr: Go back one screen. If already at the first screen on a page, go to the last screen of the previous page instead.
+scr: Go forward one screen. If already at the last screen on a page, go to the first screen of the previous page instead.
-page: Go back one page. Wraps around to the last page if you try to go back from the first page.
+page: Go forward one page. Wraps around to the first page if you try to go forward from the last page.
OK: Finish browsing and go back to the main Dokusha screen.

You can tap any JIS character in the JIS Browser screen to get more information. For Kanji characters, this takes you to the corresponding Kanji Details screen. For hiragana and katakana characters, it gives you the character's romanization. For all other characters, it simply displays the JIS code.

Here is a breakdown of what is in each JIS page:

Pages 21 and 22 - punctuation and graphic symbols
Page 23 - numbers and letters
Page 24 - hiragana
Page 25 - katakana
Pages 26 and 27 - Greek and Cyrillic characters
Page 28 - graphic symbols and small letters
