Subject: need dynamic array on heap

I want to put aside a chunk of the heap and then index it by byte like 
an array of byte.  I could just declare it as some type like 
'array[1..64000] of byte', but I want to use GetMem so that the array will
really be dynamic (I don't want to use 64K each time).

So, I'm trying this:

program Test;
  type
    C_arrayType = array[1..1] of byte;
  var
    Buff : ^C_arrayType;
  begin
    GetMem( Buff,1000 );
    Buff[1]^ := 2;
  end.

But I get 

  Buff[1]^ := 2;
      ^ Invalid qualifier

so does anyone know, is this sort of thing possible?  Can you do this
easily in C?

Thanks,
