type PChar = ^Char;
Description
The PChar type is a pointer to an Char value.
It can also be used to point to characters within a string, as in the example code.
As with other pointers, integer arithmetic, such as Inc and Dec can be performed on a PChar variable, also shown in the example.
Notes
PChar is principally used when processing null-terminated (C-like) strings.
At the current time, Char variables are identical to AnsiChar variables, being 8 bits in size.

Example code : Display all characters in a string
var
myString : string;
myCharPtr : PChar;
i : Integer;
begin
// Create a string of Char's
myString := 'Hello World';
// Point to the first character in the string
i := 1;
myCharPtr := Addr(myString[i]);
// Display all characters in the string
while i <= Length(myString) do
begin
ShowMessage(myCharPtr^);
Inc(i);
Inc(myCharPtr);
end;
end;
