Because KeyBook does not allow the text within a book to be modified or added to, just press 
ENTER to confirm the prompted option. KeySoft then prompts: 
"Extended ASCII character option? Currently Retain." 
The most common writing system used by computers is ASCII. In this system, each letter, number, 
and commonly used punctuation mark is represented by a number between 0 and 127 (Since the 
system was developed in the U.S., "commonly used" means commonly used in the U.S.) There is 
no way to represent accented characters and other special symbols, so the system has been extended 
with numbers greater than 127. The Extended ASCII option controls how KeyBook interprets these 
characters represented by numbers greater than 127, so-called "extended characters." 
Sometimes extended characters occur not because they are accented characters or special symbols, 
but because the file has been transmitted through a communications system that has added a "parity 
bit" which in effect has added an offset to some of the characters. To adjust for this, use the 
"Convert to standard ASCII" option, by pressing C, followed by ENTER
Sometimes the extended characters are used purely for visual effects such as boxes around 
paragraphs, etc. In these cases the book will be easier to read if the extended characters are removed 
altogether; use the "Ignore" option for this. 
To retain the extended characters when the book is opened, select "Retain" by pressing R, or press 
ENTER as this is the default setting. If you select Retain, another option is presented: KeySoft 
prompts: 
"Extended character set? Currently ANSI." 
More than one system has been used for extended characters; therefore you must tell KeyWord 
which one to use for this book. The options are the "ANSI" character set and the "MSDOS" 
character set. If you don't know which one to use, try one and if the extended characters do not 
come out correctly, try the other. For the "MSDOS" set, press M followed by ENTER. For the 
"ANSI" set, press A followed by ENTER
KeySoft will now prompt: 
"End of list." 
When you have made all your selections, press ESCAPE

Reading Books Stored on Other 
Drives. 
The Flash Disk is shared by the other programs like KeyWord and KeyMail, and its contents are 
preserved much like files on a conventional hard drive. There is an empty folder called My Books 
provided on the Flash Disk. Many users who have a large collection of books prefer to keep these 
on a storage card.
