Just beyond the last line of the basic program - TOP is the first free memory address, so this is copying 1,024 bytes (&400) from the first location after the BASIC code into the MODE 7 screen memory that starts at &7C00. The ! operator represents 4 bytes at a time (a word), hence the STEP 4 in the loop. Quicker than doing it 1 byte at a time.
