To write on a piece of paper, you must type WRITE followed by the name of the object upon which you wish to scribe. This must be followed by the page number. For example: "WRITE NEWSPAPER 1" would enter the line editor, entering text on your item (in this case, the newspaper) at the end of what is already on the page. To leave the line editor, simply leave a blank line. SCAN will effectively read a page of text, but will also number each of the lines to enable you to make changes.
You can erase pages of a book or newspaper by typing ERASE followed by the name of the item, followed by the page number (if more than one) to erase, e..g.. ERASE BOOK764 12 to erase page twelve of "book764" in your inventory. You may title the pages of books, tomes, letters and such, by typing TITLE followed by the item (e..g. TOME) followed by the page number (if relevant), finally followed by the text of the title. This will automatically update the table of contents (READ TOME). You can update the title of the book itself (at most sixty letters) with TITLE <book> BOOK <title>, and you can update the registered author name with TITLE <book> AUTHOR <full name>. Editing pages must be done as whole and doing so will erase titles so you need to title each page after an edit if you wish to update the contents.
If you have the authority and the skill you may also be able to write in runic script; see HELP SCRIPT for information.
