#Text.ColorBack

##Syntax Text.ColorBack ( Color : int )

##Description The Text.ColorBack procedure is used to change the current text background color. The alternate spelling is Text.ColourBack.

The Text.ColorBack procedure sets the text background color to the specified color. This is the color that surrounds characters when they are put onto the screen. On an IBM PC in "screen" mode, the color can be from 0 - 7. (You can not have the upper 8 colors as text background colors. On UNIX dumb terminals, Text.ColorBack(1) turns on highlighting and Text.ColorBack(0) turns it off. On other systems, this procedure may have no effect.

##Example Since this program is in "screen" mode, changing the background color has no immediately observable effect. When the message "Greetings" is output, the background surrounding each letter will be red.

    View.Set ( "screen" )
    �
    Text.ColorBack ( red )
    put "Greetings"

##Details The screen should be in a "screen" or "graphics" mode. If the screen mode has not been set, it will automatically be set to "screen" mode. See View.Set for details

##Status Exported qualified.

This means that you can only call the function by calling Text.ColorBack , not by calling ColorBack.
