AnsiString stores and keeps track of the string length and this has many
advantages:
*) If you need the length of a Pchar string you always need to count
character by character (until #0). This is very slow. Ansistring has it
available directly.
*) If you compare two strings for identity you can first compare
lengths. If different then strings are different too. Not possible with
pchar.
*) You can store #0 in AnsiStrings (not possible with pchar because it
indicates the end of the string).
*) You can access the last string character directly by using the
length. With pchar you have to iterate on all characters.
