Suppose I have one character code like this
A;0000;0000;0000 ("0"s is data)
and another one
AB;0000;0000;0000 ("0"s is data)
and another one
ABC;0000;0000;0000 ("0"s is data)
then this wouldn't work, would it?
I am ONLY asking to check whether I have understood
this code...nothing more! There is no hidden critism
between the lines I wrote! :))
