	B.  Internal Information
	
	    This appendix describes the meaning EDIT assigns to each possible
	byte stored in a file it is editing or printing.  
	
	    In general, EDIT stores files a normal characters.  A line feed
	(LF) is stored at the end of each line, and each line that ends a
	paragraph also has a carriage return (CR) preceeding the line feed. 
	Characters in the range 128 through 255 which include normal printing
	characters, but also greek characters, box-drawing characters, and
	other extensions to the ASCII character set are also stored normally
	and may be used in EDIT.  The only characters that EDIT treats
	specially are the characters in the range 0 (NUL) through 13 (CR). 
	EDIT does not display anything on the screen for any of these codes,
	also some of them affect the display of the text that follows them. 
	For example, LF is not displayed itself; instead, it causes the
	following character to be displayed at the beginning of the next
	line.  EDIT uses each of these characters as follows:
	
		Character			Usage in EDIT
	
		0 					Used as a marker of the cursor position
							during paragraph reformatting.  If the
							paragraph already contains this character,
							the cursor may be positioned incorrectly
							after the paragraph has been reformatted.
	
		1  (Ctrl-A)			End Bold.  Marks the end of a BOLD section of
							text.
	
		2  (Ctrl-B)			Begin Bold.  Marks the beginning of a BOLD
							section of text.  Note that it is legal to
							insert Ctrl-B and Ctrl-A around a section of
							existing text to make that text BOLD.  This
							may sometimes be easier than using Alt-B, and
							then typing the text.
	
		3  (Ctrl-C)			End Underline.  Marks the end of an
							UNDERLINED section of text.
	
		4  (Ctrl-D)			Begin Underline.  Marks the beginning of an
							UNDERLINED section of text.  Note that is
							legal to insert Ctrl-D and Ctrl-C around a
							section of existing text to make that text
							UNDERLINED.
	
	    5, 6, 7, 8			Not used by EDIT at this time, but reserved
							for future expansion.
	
		9  (HT or Ctrl-I)	Tab.  Causes the following character to be
							printed at the next tab stop.  Note that a
							tab in a line sets the left margin for the
							following lines in a paragraph.  In general,
							tab is used in the first line of a paragraph
							to set a local left margin for that
							paragraph.  
	
							It is not a good idea to insert a tab in a
							line other than the first line of a
							paragraph, because when the paragraph is
							reformatted (because characters preceeding
							the tab in the paragraph are inserted or
							deleted), the tab will be moved along with
							the other characters being reformatted, and
							this may cause the left margin to move to
							wherever the tab was moved to.
	
							It is good practice to set the tab stops and
							margins so that there will be a tab stop
							exactly at the left margin.  
	
		10	(LF or Ctrl-J)	Line Feed.  Causes the following character to
							be printted at the beginning of the next
							line.  Note that EDIT stores a LF without a
							preceeding CR on lines inside a paragraph,
							but a CR-LF pair at the end of a paragraph. 
							Thus, when a file is printed, EDIT will right
							justify lines that end with LF only (no CR).
	
		11					Not used at this time, but reserved for
							future expansion.
	
		12	(FF or Ctrl-L)	Form Feed.  Causes the following character to
							be printted at the beginning of the next
							page.  Note that the FF character is
							displayed on the screen of the PC as a little
							circle with a plus-sign under it.
	
		13  (CR or Ctrl-M)	Carriage Return.  Signals the end of the
							paragraph.  If a line of text has a CR
							character immediately preceeding the LF at
							the end of the line, that line will never be
							right justified when it is printed.
	
							CR will also turn off BOLD and/or UNDERLINE. 
							Thus, BOLD and UNDERLINE are always turned
							off at the end of each paragraph.
	
		14 through 255		Printable Characters.  All characters in this
							range may be used as the text to be displayed
							and printed by EDIT.  For a description of
							the image displayed or printed for each of
							these values, you should consult the
							appropriate PC or printer documentation.
