Need advice with LCD 2x16

If you wanted to move over an extra character to maintain alignment, why not just add an extra blank after SIGN2?

 
if (temperature2/100) =>10 then
LcdOut $FE, $c0, "OUT : ", Sign2," ", DEC (Temperature2 / 100), ".", DEC Temperature2 dig 1, " ",223,"C " 
else
LcdOut $FE, $C0, "OUT : ", Sign2,"  ", DEC (Temperature2 / 100), ".", DEC Temperature2 dig 1, " ",223,"C " 
endif

Moving the cursor can give misleading information unless you clear the display first. $C0 sets the cursor position to the beginning of the 2nd line, it does not erase what was written previously.

Let's say it is displaying 25C and the reading changes to 7C. If you move over 1 position, the 2 will still be there, giving 27C.
