Hi, Bruce,

thanks for your enlightments.

find here the answer from Melabs :

"
For special characters such as this, it is better to specify the
character using its numeric ASCII code. I believe this will work:

LCDOUT $FE,$C0," ", SDEC2 Tair, $B0, "C "

I believe you could ignore the warning and the display would be
correct, but it's always a good idea to resolve warnings as they come
up.

Solution confirmed ... and thanks to melabs.
