Srinivas,
Here is some code as an example

MODULE FooModule;
     TYPE
         MyRecord =    RECORD n: INTEGER; r: REAL END;
     VAR
         a: POINTER TO MyRecord;
         b: POINTER TO MyRecord;

     BEGIN
         NEW(a);
         b := a;
         (*both a and b point to the same memory location*)
END FooModule.
