(6 points) Consider the following code. Assuming all registers start at zero, what is the output of the program? Be exact! This question is tricky in several places. Take your time. Clearly keep track of what values are in RO and R2 as the program executes (not all boxes are needed). a. "ORIG x3000 RO: 000N LEA LD OUT LEA PUTS STI TRAP HALT RO, THING RO, LABEL -Prins R2, BLAH Fill x21 LABEL .FILL x48 THING .STRINGZ "ar" A BLAH .FILL x21 .END Program Output: b. (4 points) The following program is supposed to print the number 5 on the screen, but does not work. Explain, in 10 words or less, why it does not work as intended. Insert the code needed to make the program work as intended. DO NOT change any of the instructions. 2. .
