1. Backcolor graphics mode DOS32

Hello,
I'm relatively new at Euphoria, so maybe this is a trivial question.
However, help is appreciated!
Given the following coding (DOS32):
include graphics.e
object dummy
dummy =3Dgraphics_mode(18) =20
clear_screen()
bk_color(BLUE)
polygon(BRIGHT_WHITE,1,{{60,150},{200,150},{200,285},{60,285}})
position(11,09)
text_color(MAGENTA)
?(12345)=20
This results in a magenta number on a blue background inside a
white rectangle.
I would like to have the number in magenta on the white background=20
of the rectangle, without losing the blue background of the rest of
the screen.
Is that possible at all ? Thanks for the help!
Fritz Deneken.

Not using DOS' background color. As you saw, changing the background
color anywhere, changes the displayed background color for the entire
screen.
However, there's an easy work-around. Just draw your background as a
polygon in the color you want, then draw your white area where text is to
appear,
and display the text. Here's an example:
include graphics.e
atom x
x = graphics_mode(18)
bk_color(BRIGHT_WHITE)
position(10,10)
text_color(GREEN)
puts(1,"Green")
position(12,10)
text_color(RED)
puts(1,"Red")
position(14,10)
text_color(MAGENTA)
? 12356

Irv

OF COURSE !! Now why didn't I think of that one?
Thanks, Irv!
