<lang gwbasic>10 REM GW Basic can switch VGA modes
20 SCREEN 18: REM Mode 12h 640x480 16 colour graphics</lang>
=={{header|ERRE}}==
ERRE language (for PC) supports these modes (accessible with SCREEN procedure of PC.LIB library):
* SCREEN(0) => text 80x25 or 40x25 -- standard
* SCREEN(1) => 320x200 4 colors
* SCREEN(2) => 640x200 2 colors
* SCREEN(7) => 320x200 16 colors
* SCREEN(8) => 640x200 16 colors
* SCREEN(9) => 640x350 16 colors
* SCREEN(10) => 640x350 for MDA monitors (if you have one .....)
It's possible to activate all VGA and SVGA modes using DOS interrupts. On the distribution disk there is an example to activate 320x200 - 256 colors.
ERRE language (for C-64) support high resolution graphic (320x200) using HGR.LIB library.
=={{header|Icon}} and {{header|Unicon}}==
The following works in both languages on X-windows based systems and assume
<tt>xrandr</tt> is installed:
{{trans|UNIX Shell}}
<lang unicon>procedure main(A)
mode := A[1]
if \mode then system("xrandr -s " || \mode || " >/dev/null")
else system("xrandr -q") # Display available modes
end</lang>
