I have a code that lets user input 5 numbers and they will be added up and the sum will be displayed. If the user hits ENTER the sum will be displayed and if they press q the program will halt. I am new to LC3 and I never understood how to change a value from ASCII to decimal. I don't know if the value is not being stored or if the sum operation is not right. Anyone know how to do this?
I already tried to use x0030 (48) and subtract it from the sum but it does not work.
