The Problem: Take two numerals from the console and print the sum. • The Algorithm (Twenty-four lines starting at x3000): 1. Load into register R3 the value x30 from the third memory cell following the TRAP X25 (HALT) at the end of the program. 2. Use two instructions and no new registers to negate that value. 3. Call TRAP x23 (called IN on page 543 of Appendix A of the text.) 4. Add R3 to RO leaving the result in RO. 5. Store RO's value to the first memory cell following HALT. 6. Load into RO the value xA from the fourth cell after HALT 7. Call TRAP x21 (called OUT on page 543 of Appendix A). 8. Call TRAP x23 again. 9. Add R3 to RO leaving the result in RO. 10. Store RO's value to the second memory cell following the HALT. 11. Load into RO the value xA from the fourth memory cell following HALT 12. Call TRAP x21 13. Load into a first chosen register the first number. 14. Load into a second chosen register the second number. 15. Add the two numbers, putting the result in RO. 16. Load into register R3 the value x30 from the third cell after HALT 17. Add R3 to RO leaving the result in RO. 18. Call TRAP x21 19. Call TRAP X25 (HALT) 20. Place x0000 (zero) here (this saves space for the first number). 21. Place x0000 (zero) here (this saves space for the second number). 22. Place the value x0030 here. 23. Place the value x000A here (this is the newline character). When the program is started, it prints a prompt and waits. To enter a number, first click once on the console. It will turn light blue. Then type a single-digit number. The second prompt appears right away. Just type another single-digit number (no second click; no other keys pressed).
