# PART 3 (ReadFile)

# # You will read characters (bytes) from a file (lab2_data.dat) and print them. Valid characters are only spaces (ASCII code 32),

#Exclamation points (ASCII code 33), and uppercase letters (A-Z).

#Lower case letters should be converted to uppercase and eveything else should be discarded

#The expected output should be in one line and read: THIS WAS A SUCCESS!

# $a1 : address of the input buffer
