Configuring LIST
______________________________________________________________________________
Screen Colors
The screen's lines may be in one of three different colors:
o the 'special' color for the top status line and the
bottom command line
o the 'normal' color for the file's text windows
o the 'bright' color for lines with Find/Scan text,
and for the upside-down question mark in 7-bit mode
There is a pair of function keys assigned to each color. You use
these function keys at any time to change the background and
foreground colors temporarily, or use the Alt-C cloning command to
make the colors permanent. Alt-C requires that the LIST.COM program
file be on the current drive and in the current directory unless you
are using DOS version 3.3 or later. With DOS 3.3, the program file
may have any name and may reside in any subdirectory.
The border is not changed. The foreground color applies to the
color of the characters.
è You may clone a second set of text colors for the second, and any
other windows that you may create.
The color attributes may be changed by using these function keys:
For the main body of text:
F5 - background color
F6 - foreground color
For the top and bottom lines:
F7 - background color
F8 - foreground color
For the line with Find/Scan text:
F2 - background color
F4 - foreground
Once you have decided upon the colors, use the Alt-C key combination
to change the LIST.COM program file. This process is described
below.
Cloning
The screen colors, the display retrace testing (M), the file sharing
(S), ruler (Alt-R), and other options may be permanently set in the
program COM file by using the Alt-C cloning function.
For cloning to take effect, the program should be called LIST.COM
and on the current drive and in the current directory.
There are THREE versions of the LIST program file. One is the
normal full program, which is LISTR.COM. The other, which is called
LISTS.COM, is a slightly smaller file that excludes the Help screen.
The third is LIST PLUS, found as LIST.COM. You may use any of the
three COM files for cloning. After cloning, you may continue
viewing the file. Several of the command toggles are also
'clonable'.
The values and toggles that are cloned are:
M = Mono monitor, affects retrace testing. If you see
"snow" on your color monitor, turn off this option
Alt-S = file(s) are shared
W = Wrap long lines
8/7/* = display all 256 values, or 7-bit, or special case
K = flush Keyboard each time a command is read
è Alt-H = hex dump display, like the DEBUG format
Alt-J = toggle "junk" filter, add LF to CR, fix backspaces
Alt-L = set on to force preloading (reading) of the entire
file before any lines are displayed, Default is OFF.
Alt-N = toggles screen saving (see Alt-X) feature
Alt-R = toggle columnar ruler on top line
Alt-T = toggle expansion of TAB characters (also Ctrl-I)
Alt-V = number of filenames per line (up value) and sort method
F2 = change background color for Find/Scan text
F4 = change foreground color for Find/Scan text
F5 = change background color for main body of display
F6 = change foreground color for main body of display
F7 = change background color for top and bottom lines
F8 = change foreground color for top and bottom lines
Note: Be sure you have no other copies of LIST.COM which are
accessible (because of an APPEND type of utility). If you are
familiar with the DOS utility DEBUG, you may want to modify LIST in
that way. This is described in the next section.
