Here is an example. First I used ACLS to clear everything off the sceen. Next I put XSCREEN 2 to use just the top sceen. Then I used BGSCREEN to make some room for the BG. Then I made an array named BG to store the background in using DIM BG[0]. After that I loaded layer 0 of a backround I made called "HOUSE" into my BG array. (The 0 is so that it won't display a dialog flag when loading.)
