Changes to POINTERMATH

Now the operator[] of typed pointer returns the dereferenced pointer to type(ref to value).

Thanks to DiamondShark.

A sample

program myprogram;

procedure pf < T> (cnt:integer);
p:pointer;
ptype:^T;
valueA:T;
i:integer;
begin
GetMem(p,cnt*sizeof(T));
ptype:=p;
for i:=0 to cnt-1 do ptype[i]:=valueA;
FreeMem(p);
end;

begin
pf < boolean> (100);
pf < integer> (200);
pf < double> (300);
end
