wanna place a screen independent button with at m1 x m2 button 'hi' []

Hi , is it possible to use variables instead of integer value for at command ? Project : REAL screen independent GUI R E B O L [title 'screenindependent'] x: system/view/screen-face/size/1 ;; Width in a variable y: system/view/screen-face/size/2 ;; Height in a variable x1: x / 100 ;; 100 percentage steps y1: y / 100 x2: x1 / 2 ;; half screen size is now 100% y2: y1 / 2 print x ;; screen full size print y print x1 ;; 1 % of it print y1 print x2 ;; if you use a half screen then half is now 100% size and x2 is 1% of it print y2 m1: x2 * 75 ;; try to set a variable m1 that contains 75% of the window Width m2: y2 * 10 view center-face layout [ size system/view/screen-face/size / 2 ;; window IS 50% of machine screen size at m1 x m2 button 'i am screen independent' [] ;; want to place a button on 75% width of the main window ]

I'd suggest using a function to do the translations for you. In this case I've wrapped the function in it's own context with the base unit sizes (I tend to do this to isolate words that aren't used anywhere else). https://gist.github.com/rgchris/2fc9af8ee841514cb1f06b9cd00d8fef

Hey Chris , that code you made is really clever. I will try it.
