Part 1 (movzx/movsx practice). Copying Smaller Values to Larger Ones Declare two 16-bit variable to store 100 and -100. Then move them to 32-bit registers. Catch the screenshots from running in debugger mode to identify the value saved in each register is correct. How to verify the values are correctly moved?
