   Is it permissable to call NewHandle (or NewPtr) with 0 as an argument?
   For instance:

	{
            Handle myHandle;

   	    myHandle = NewHandle(0L);
	}


   And then make myHandle bigger with calls to SetHandleSize() when needed.

   I have not found anything in any Apple literature to warn against this
   technique. But I am concerned that the call to NewHandle() may lead to 
   problems.
