It is a little more complicated.  Let's say I have
these codes:
 data = 12345;
 printf("%d",data);  // LCD scr displays "12345"
 data = 9;
 printf("%d",data);  // LCD scr displays: "92345"
for the second printf, instead of displaying "9", it
diplays "92345".  It is hard to calculate how many
digit the "data" field has to provide the blank
space.This is the reason why I have to clear the
entire LCD to get rid of this kind of problems.  I
thought of keeping an image of the LCD on RAM, but
this requires lots of RAM space.

Thomas
