Convert the temperature to an absolute value.
From the manual

4.17.4. ABS
ABS returns the absolute value of a number. If a byte is greater than 127 (high bit set), ABS will return 256 - value. If a word is greater than 32767 (high bit set), ABS will return 65536 - value.
B1 = ABS B0

Then you are back to IF < 10.....Just remember your sign...

I have good results, based on this "$FE, $14 - Move cursor right one position" :

Code:

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," ", $14, DEC (Temperature2 / 100), ".", DEC Temperature2 dig 1, " ",223,"C " 
endif

Thanks !!!

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

Code:

 
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.

Thank you !
I try my code in ISIS and work ok ; it' possible, in 'real life' to work bad...but I do not have -yet- the hardware.
