Hey,

there are several ways of pulling this off, the most straight forward one is to use 2 variables to store width and height from gpu.getResolution.

local w, h = gpu.getResolution()    --# width and height

if w == 80 and h == 25 then
  c.beep(500, .5)
end

If you don't want these 2 variables messing with your current scope simply surround the if statement with a do...end block.

do
  local w, h = gpu.getResolution()    --# w and h don't override any previous variables of the same name
  if w == 80 and h == 25 then
    c.beep(500, .5)
  end
end
--# here w and h are not visible anymore
