DONE x300A
NUMS x300C
SUM x3011
1) What is the address of the symbol LOOP? x3004
2) What is the value of R1 after the second line of code is executed? x300C
3) How many times is the loop executed? infinte
4) R2 points to successive memory locations in the array as the loop iterates (T/F)?
F
5) When the program halts, what is the content of the location with label SUM in decimal?
