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! :))
