    This information is offered to those of you who wish to modify  LIST 
    in special ways.  You do not need this information to use LIST.   An 
    alternative to cloning  is to use  DEBUG to make  permanent changes. 
    Also, a special customization program called LISTOPT is available to 
    registered and licensed users.  Subtract hex 100 if  you are using a 
    a file editor instead of DEBUG. 
 
    Here is a list of key items and their addresses:

    When the  Find/Scan command  is used,  the next  line which contains 
    that text is highlighted using the 'bright' color, and is placed  in 
    row 9 of the screen.  You can change the row by Altering the byte at 
    location 13C which is normally '08', one less than the row.

    The following offsets change from version to version. Look for the 
    eye-catchers to be sure of the offset: 
 
    Key table       0473    'WHAT'  Eye catcher 
                    0477    0026    Key command table 
    Routines        057C    'WHERE' Eye catcher 
                    0581    xxxx    Command routines 
 
    Examples of using DEBUG can be found in the DIALER.PAT and 
    COLORS.PAT files. To use them, copy LIST.COM to the current 
    directory and issue the DEBUG command. For example: 
 
            DEBUG <DIALER.PAT

 Reassigning keys 

    LIST performs a function for every character that can be entered  at 
    the command line prompt.  There  are 128 regular characters and  131 
    extended characters.  The regular characters are numbered from 0  to 
    127, and  they include  the letters  A-Z, a-z,  the numbers, and the 
    rest of  the usual  single characters  found on  your keyboard.  The 
    extended characters represent special function keys and combinations 
    of keys, such as F1, Alt-X, Ctrl-A, and the cursor positioning keys. 
 
    The  WHAT  table  in  LIST  has  a  one  byte  entry for each of the 
    characters.  This byte is a number from 0 to 57 that represents  the 
    identification of a routine that performs a function. 
 
        For example,
