Write a 68000 assembly program to subtract two strings of A15 ASCII characters. The first string is stored starting at $502030. The second string is stored at location $302510. The ASCII character in location $502030 of string 1 will be subtracted from the ASCII character in location $302510 of string 2, [$502031] will be subtracted from [$302511], and so on. Each time there is a match, store $EEEE onto the stack; otherwise, store $FFFF onto the stack. Assume supervisor mode.
