         Screen Swap
         ------ ----

   The Commands :

    *SWAP   - Swap screens
    *STORE  - Store screen
    *RECALL - Recall screen
    *CLEAR  - Clear stored screen

   This utilitity enables you to
work on two Mode 4 or Mode 5
screens at once. *STORE stores the
current screen in Sideways RAM
from where it can be later
recalled with *RECALL. *SWAP swaps
the current screen with the
'sideways screen' and *CLEAR
clears the 'sideways screen'

   These commands will also work
in Mode 7, but don't forget they
swap ALL memory from &5800 to
&8000 !
