Okay, your problem is more clear now :)
I can't test now, but could you use something like:
procedure lcd_bold'put(byte in char) is
if ((char >= '0') & (char <= '9') then
// load the appropriate char here at location 0
lcd = 0
else
lcd = char
end if
end procedure
and then write to lcd_bold in stead of lcd.
Too bad you only have 8 custom chars and you need 10... You could
create a better performance if you use all 8 chars and remember which
ones are already loaded. This will need pic memory to rembember the
chars loaded and more complex code...
