CRT is a small program that allows you to change the control the video,
border, background and foreground colors. There are seven subroutines
in CRT. They are:
BORDER - which sets the border color.
CLEAR - which clears the screen and sets new foreground
and background colors.
COLOR - now just as fast as Clear but it does not wipe the
text off the screen as it changes attributes.
MONO - {has been deleted since version 3.1; now uses
automatic video detection}
BRIGHT - Enable the setting of the background to bright
colors just like the foreground
VGA - Set number of lines displayed on the screen
EGA - Set number of lines displayed on the screen
GREY - Turn grey scale summing ON or OFF
The color set values for the video system are:
0 - black 8 - dark gray
1 - blue 9 - light blue
2 - green 10 - light green
3 - cyan 11 - light cyan
4 - red 12 - light red
5 - magenta 13 - light magenta
6 - brown 14 - yellow
7 - white 15 - bright white
To use CRT to set a mono screen, you would use:
CRT COLOR parm1 parm2 <ENTER>
where parm1 is the foreground and parm2 is the background.
valid options for mono are:
MONO 7 0 - for a normal screen
MONO 1 0 - for all underlined characters
MONO 0 7 - for reverse video characters
MONO 15 0 - for bright characters on a black screen
To use CRT to set borders, you would run it as follows:
CRT BORDER parm1 <ENTER>
where parm1 is one of the color set values from the chart above.
To use the other features, type in one of the following:
CRT CLEAR parm1 parm2 <ENTER>
or
CRT COLOR parm1 parm2 <ENTER>
where parm1 is the foreground color that you wish to use and parm2 is
the background color.
As an example, to clear the screen and set the colors to green text on
a black background, you would use:
CRT CLEAR 2 0 <ENTER>
************************************************************************
BRIGHT: ON or OFF are the options. When set ON, the CLEAR or
COLOR command can set the background to a 'bright'
color such as yellow (14). For example, to set black
text on a yellow background you would use the command:
CRT COLOR 0 14
VGA : Set the length of the screen display. Valid options are:
50, 43, 28, 26, 25, 21, 14 or 12. Both 25 and 26 will
display 25 lines only in different fonts. All of these
options may not work with every video board.
EGA : Set the length of the screen display. Valid options are:
43 or 40
GREY: ON or OFF are the valid options to control the grey-scale
summing feature of VGA video boards
I hope that you get lots of use out of this small utility and let me
hear your comments or suggestions for improvements.
