- 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.
