The function SCREEN returns the start address of the screen.

SCR_BASE is the same as the second variant of SCREEN, defaulting to #0.

NOTE:
The FN Toolkit version allows you to specify a channel - if the channel is specified, then the start address for the screen on which that channel is open is returned.  Thus SCREEN(#3) can be used to find the start address of the second screen if that is where #3 is located.
