Set 2 variables, x and y. Your first drawtext will be at x and y. The other elements after it can be x+10.0 and y+10.0 and so on. That way, if anybody wants to move the entire thing, they just need to touch the x and y variable.
So… for example… Very basic, but I hope it gets the point across.
local x = 0.5
local y = 0.5
drawTxt(x, y, "helllo today")
drawTxt(x+0.05, y+0.05, "oh hi")
