Additional Information
- SS.AlfaS maps the screen into the user address space. The call requires a full block of memory for screen mapping. This call is only for use with VDG text screens handled by VDGINT.
- The support module for this call is VDGINT.
- Warning: Use extreme care when poking the screen, since other system variables reside in screen memory. Do not change any addresses outside of the screen.
