I am not sure there is, what you probably should do is if your line is because your doing calculations inside a function param then do them before, example:
CreateWindow((graphicswidth()/2)+(MouseX()/3)+3,graphicsheight()/2)+(MouseY()/6))
etc etc
do this instead:
local wX% = (graphicswidth()/2)+(MouseX()/3)+3
local wY% = (graphicsheight()/2)+(MouseY()/6)
CreateWindow(wX,wY)
It makes it far easier to read and to debug at a later date. I usually use temporary calculation variables like this if I am doing anything more than +1 etc, as you can document them.
