Screen width vs window width

In the question "Screen out mobile users?" (asked by John on 4/1/16), Justin offered a solution and called the variable screen_width.  It appears to be window_width rather than for the full screen.  Is there a way to get the width of the full screen?  (Version 8.4.8)

Also, is sys_ScreenWidth available in v8?  Does it return the screen or the window?

sys_ScreenWidth returns the width of the window.  It is not built into v8.4.8, but as Justin's code shows, you can achieve the same effect as having sys_ScreenWidth with a simple free format question.

As for reading the screen width, you can store this value with just a slight modification to Justin's code:

<input name="screen_width" id="screen_width" type="hidden" value="">
