First Frame width is set by command cols = "160,*"
160 = +- 5 cm & If * is left out 2nd col dissappear
if command col = "160,160" then col 1 = col 2
whole screen
Thus * means fill rest of space of screen while 160 tells
size of column if cols = "*,100" then
2nd frame = 100 and 1st fills rest of screen
