Problem is that the code HAS TO BE enclosed by iow.xtop. Otherwise screen base may even change between the call to know the screen base, and the read or write operation. That would change if graphical operation were done directly in the save area, but that is only for sometime in the future. Once that is done, iow.xtop would no longer be necessary, and doing things in Sbasic would be safe again. Joachim
