# This program gets two single-digit numbers, A and B, from the user
# Then prints out the numbers A through B
0 LOADI A 1  # Get the number 1 into register A
1 LOADI B 48  # 48 is int value of '0', pseudo-constant
2 IN C 0  # Get starting point in ASCII
3 SUB D C B  # Get integer value of input character
4 IN C 0  # Get ending point in ASCII
5 SUB E C B  # Convert ending from ASCII to int val

# Starting value is D, ending value is E
6 LTE D E  # (D <= E)
7 NOT  # !(D <= E) --> (D > E)
8 CJMP 13  # If (D > E) from above, exit loop
9 ADD C D B  # Convert D as int into ASCII
10 OUT C 15  # Print out the number
11 ADD D D A  # Increment D
12 JMP 6  # Go back to the top of the loop
