Need advice with LCD 2x16

[fratello]

Hi again ! For the start I want to thank you all for helping me so many times ! It's a great forum this one ! All my good thoughts for each of you !
I made for one friend one thermometer, with two DS18B20 and LCD 2x16 display.
I search all over the forum but I don't find the answer : how can I keep the value on display in the same position, even the number of characters change, from 3 (18,7) to 2 (9,4) ? I want to keep both temperatures value on same column. Hope the picture help to understand...
Now I use this command for display :

LcdOut $FE, $80, "IN  :  ", Sign1," ", DEC (Temperature1 / 100), ".", DEC Temperature1 dig 1, " ",223,"C " 
LcdOut $FE, $C0, "OUT :  ", Sign2," ", DEC (Temperature2 / 100), ".", DEC Temperature2 DIG 1, " ",223,"C "

Thanks in advance !

From the manual

Note that there is a command to move the cursor to the beginning of the second line of a 2-line display. For most LCDs, the displayed characters and lines are not consecutive in display memory - there can be a break in between locations. For most 16x2 displays, the first line starts at $0 and the second line starts at $40. The command:

LCDOUT $FE, $80 + 4

sets the display to start writing characters at the forth position of the first line. 16x1 displays are usually formatted as 8x2 displays with a break between the memory locations for the first and second 8 characters. 4- line displays also have a mixed up memory map, as shown in the table above.

So set the "static" text to start where you want it and let the VARs follow.

Thanks for reply !
I made this change :

LcdOut $FE, $C0, "OUT :  ", Sign2," "
LcdOut $FE, $C0 + 9, DEC (Temperature2 / 100), ".", DEC Temperature2 DIG 1, " ",223,"C "

and the position of first character of second temperature don't move. But I want to keep the position of the last character ; maintaining the alignment to the right !

You could add a leading zero if the value is less than 10 or if the value is less than 10 the position is X else the position is Y.

... if the value is less than 10 the position is X else the position is Y.

I think this is the answer ! I will try.

I use this code :

 OWIn DQ2, 2, [temperature2.byte0, temperature2.byte1]  

If Temperature2.15 then       
  Temperature2= ~Temperature2 +1
  Twist2 = 1
Endif
 
Dummy2 = 625 * Temperature2
TempC2 = DIV32 10 
TempC2 = (Temperature2 & $7FF) >> 4
Float2 = ((Temperature2.Lowbyte & $0F ) * 25 )>>2
Temperature2 = TempC2*100 + Float2

If Twist2 then
  V2= 10000 - Temperature2               
  Twist2 = 0
 else
  V2= 10000 + Temperature2
EndIf

If V2 >= 10000 then                           
  Temperature2=V2-10000                   
 else                                   
  Temperature2=10000-V2                   
EndIf

How can I say "if temperature2 > 9.99 'C or temperature2 < -9.99 'C" ?
