 Context sensitive help can be obtained  
 by pressing the F1 key after a prompt   
 for a command argument, or after        
 pointing to a command on the menu.  Help
 from the menu provides a command        
 description, while help from a prompt   
 provides a description of the keys used 
 in response to the prompt, followed by a
 command description.

 adhering to the following pattern:      
                                         
 1.  Frequently used commands --         
     unshifted function keys.            
                                         
 2.  File commands -- Ctrl shifted       
     function keys.                      
                                         
 3.  Find/Replace commands -- Shift     
     shifted function keys.              
                                         
 4.  Cut & Paste commands -- Alt shifted 
     function keys.                      
                                         
 5.  Miscellaneous commands -- Remaining 
     shifted/unshifted function keys and 
     Alt shifted letter keys.

  "C" language programs, the editor      
  displays all the function names that   
  start in the first column.  In         
  languages like COBOL, where the first  
  available column is reserved for       
  special use, the editor displays all   
  the lines that start in the first      
  available general purpose column       
  (column 8 in COBOL), with an alphanume-
  ric character.  In other languages, the
  editor displays all the lines that     
  begin in the first available column    
  with an alphanumeric character.

  Controls visibility of Tabs an End of  
  Line (EOL) marks.  When "off", the Tab 
  and EOL marks become invisible.        
 CURSOR SIZE                             
                                         
  The cursor size is defined in terms of 
  the top scan line and the bottom scan  
  line.  The  value for each scan line   
  can be between 0 and 7 for the systems 
  equipped with a color/graphics adapter,
  and between 0 and 13 for a monochrome  
  adapter or EGA.                        
 TAB DISPLAY CHARACTER                   
                                         
  Defines a character to be used to      
  identify tab marks in text.  Can be    
  changed by providing ASCII code (1 -   
  254) for the new character.  Use       
  Visible TAB/EOL Marks parameter to make
  tab marks visible/invisible.           
 EOL DISPLAY CHARACTER

  Switches EGA Rows Mode between 43 rows 
  and default.  At default setting, the  
  editor comes up in the number of rows  
  of the operating system at the time of 
  startup.  Otherwise, the editor comes  
  up in 43 rows, if EGA is sensed.       
 VERTICAL SCREEN SPLIT

  The suppress "snow" parameter indicates
  whether it is necessary to suppress the
  "snow" on the screen.  The screen      
  "snow" results from direct screen      
  updates.  The IBM PC/XT with standard  
  color/graphics adapter is one of the   
  machines that requires "snow"          
  suppression.  This parameter should be 
  set to "off", if there is no problem   
  with the screen "snow".

 FILE NAME EXTENSION                     
                                         
   This program uses the file name       
   extension to determine the file       
   format.  The extension cannot be      
   specified for format 1, because it is 
   the default format.                   
 OTHER PARAMETERS Submenu                
                                         
  Defines the default values for the     
  Insert Mode, Auto Indent Mode, Search  
  Letter Case Distinction, and File Name 
  Extension.  Also defines the Average   
  Line Length, Maximum Line Length, Help 
  File Specification, and Exe File       
  Specification.                         
 INSERT MODE (on/off)                    
                                         
  Defines the initial Insert mode.  When 
  "on", the entered characters are       
  inserted in the text.  When "off', they
  overwrite the existing text.           
 AUTO INDENT MODE (on/off)               
                                         
  Defines the initial Auto Indent mode.  
  When "on", each new line is indented by
  the number of tabs in the previous     
  line.                                  
 SEARCH LETTER CASE DISTINCTION (on/off) 
                                         
  Defines the initial Search Letter Case 
  Distinction mode.  When "off", the     
  lower and upper case letters are       
  considered to be the same during the   
  text search.                           
 CURSOR RUN-ON INHIBITION                
                                         
  On/off switch controlling cursor run-on
  inhibition.  When this parameter is on,
  the program clears the keyboard buffer 
  of all the consequitive occurrences of 
  the same character, in order to inhibit
  the cursor run-on.  The cursor run-on  
  occurs in some routine operations on   
  4.77 MHz PCs, when a key is held down  
  for a period of time.  On faster       
  machines, it seems to occur only during
  resizing of windows.  This parameter   
  does not noticeably affect  the program
  speed.                                 
                                         
  When this parameter is on, the keyboard
  macros require delay factors.  If you  
  use the keyboard macros, we recommend  
  that you turn this parameter off on    
  faster machines, and experiment on     
  slower machines to decide whether to   
  turn off this parameter, or to insert  
  delay factors into your macros.        
 DEFAULT FILE NAME EXTENSION             
                                         
  The Default File  Name Extension is    
  used to append the user supplied file  
  name specification, when extension is  
  omitted.  Should be set to NONE, if    
  this is not desirable.                 
 AVERAGE LINE LENGTH                     
                                         
  The average line length is used to     
  divide the available memory between the
  line pointers and text.  The memory is 
  allocated so that the text memory will 
  be exhausted approximately at the same 
  time as the available number of lines. 
 MAXIMUM LINE LENGTH                     
                                         
  Defines the maximum text line length,  
  which must be between 3 and 16,383     
  characters.                            
 HELP FILE SPECIFICATION                 
                                         
  Identifies the name and location of the
  Help file, which is used for the       
  on-line help.                          
 EXE FILE SPECIFICATION                  
                                         
  Identifies the name and location of    
  this program's executable file.  It is 
  needed to save the parameter settings. 
 SAVE NEW SETUP                          
                                         
  Saves the current parameter settings in
  the Executable file.                   
 BEGIN SEARCH/REPLACE                    
                                         
  Begins the search/replace process.     
 RESET TO DEFAULTS                       
                                         
  Resets the search/replace parameters   
  to the initial defaults.               
 SEARCH LETTER CASE DISTINCTION          
                                         
  Switches letter case distinction in the
  search between on and off.             
 SEARCH DIRECTION                        
                                         
  Switches the search direction between  
  up and down.                           
 LINE RANGE                              
                                         
  Sets the line range for the search.    
 COLUMN RANGE                            
                                         
  Sets the column range for search.      
 NUMBER OF OCCURRENCES                   
                                         
  Sets the number of occurrences to be   
  found/replaced.                        
 CONFIRM REPLACEMENT                     
                                         
  Switches the request to confirm        
  replacement between on and off.

  If the first pressed key is not cursor 
  control, F5, or back space, the default
  prompt string will be erased.          
                                         
  Initially, the prompt comes up in      
  overwrite mode.  The overwrite mode is 
  indicated by a line cursor.  The insert
  mode is indicated by a block cursor.   
                                         
                                         
                                         
                                         
                                         
                                         
 FILE NAME REQUIREMENTS                  
                                         
  A file name specification must be a    
  valid MSDOS specification.  The default
  drive and directory are the logged on  
  drive and directory.  If specified, the
  drive and directory must  exist.  The  
  name and extension part of the         
  specification may contain wild card    
  characters (* and ?) for GET FILE and  
  INSERT FILE commands.  If the wild card
  characters are used, all the files     
  matching the specification will be     
  displayed in the form of a menu, at    
  which time the desired file can be     
  selected.                              
                                         
  If the file name extension is omitted  
  and the Default File Name Extension    
  parameter is not set to NONE, the      
  default file name extension will be    
  appended.                              
                                         
  If the drive and directory are omitted,
  the current directory is searched      
  first.  Then, an attempt is made to    
  obtain the  drive and/or directory from
  the environment variable of the same   
  name as the file name extension.       
  Finally, the PATH variable is checked. 
  If the specified file is not found, a  
  new file in the current directory is   
  assumed.                               
                                         
  Use DOS Set command to set your        
  environment variables.                 
 DIRECTORY SPECIFICATION REQUIREMENTS    
                                         
  A directory specification must be a    
  valid MSDOS file name specification,   
  containing wild card characters (* and 
  ?) in the name and/or extension part.  
 FILE DIRECTORY MENU                     
                                         
  Use the keys shown on the message line.
  Selection of a name will result in     
  bringing the corresponding file into   
  memory, as in the GET FILE command.  If
  the directory display resulted from the
  INSERT FILE command, the selected file 
  will be inserted.                      
 CONTRACT WINDOW Mode                    
                                         
  Use the keys that are shown on the     
  message line to contract the current   
  window.                                
 EXPAND WINDOW Mode
