Given that the ASCII codes for 'A' through 'Z' are x41 through x5A; and the codes for 'a' through 'z' are x61 through x7A: which of the following operations would force the
character stored in R0 to upper case - i. e. convert a character stored in R0 from lower case
into upper case, or preserve the case if it was upper case already (so ‘a’ would become ‘A’,
and ‘A’ would remain unchanged).
Note: the LC-3 stores ASCII characters in the lower byte of a 16-bit word, with the upper byte
set to zero.
ANSWER: and R0 with x005F
*** Can someone explain how this is the answer ***
