Pointers are best avoided, but sometimes you just have to use them! 

You can use PChar to extract the string, as described in this excellent
article http://www.delphibasics.co.uk/Article.asp?Name=Pointers by Neil
Moffat which contains much more useful information about using pointers.

Subject: From pointer to string

Pointer in Delphi is one of the things that I'm not
so sure about anytime I use one.

Suppose I have a data buffer, and I'd like to copy
byte 10 to 20 of the data buffer to a string. What
is the best way to do it?

var Buf: Array [0..65535] of Byte; s: String;
begin
  // modify value in buf
  ...

  // How to copy Buf[9..19] to String s?
  s := Copy(Buf, 9, 10); // this gets an "Incompatible types" error

  // Use s here
  ...
end;

Best regards,
Jack
