addr

Determines the address of a variable.

Example:

  var
   i : integer;
   p : pointer;
 begin
   i := 500;
   p := Addr(i);

   WriteLn(Integer(p^)) ;
   WriteLn('"a" is at the following address:', PtrInt(p));
 end.

Alternative

You can use @ instead of Addr(...).

The two examples below do the same thing.

   p := Addr(i);
   p := @i;

Where @ can also be used to determine the addresses of procedures and functions.
