You can have as many DL's as you wish, using the jump/vertical blank
instruction at the end of the DL to tell ANTIC where your new DL is
located. When placing your new DL (page six, unless used for other
routines, is a good protected place to put it), do a POKE 559,0 to
disable the DL fetch instructions, then POKE it with the proper value to
turn it back on afterwards. Be inventive and create your own screens
with varied lines of text and graphics.

I suggest that you read De Re Atari and Your Atari 400/800 for more
information. The latter has a few good examples of altered display lists
and tells how to create them. Two DL utilities are The Next Step from
Online and Tricky Tutorial #1 from Santa Cruz.
