Suppose we have ASCII data saved in memory that corresponds to a person's firsename. The name is all lower case letters $-$ write a loop that reads thr the characters $($starting at memory address $000),$ changes their case to uppercase, and then writes the data back to the same memory address. The lo should terminate $($branch to a label called "END"$)$ if the null character is detected, indicating the end of the string. $($I am not expecting you to have mem the ASCII table $-$ search for it to find the relation between upper and lower case letters, as well as how the null character is defined$).$
