any1 know why this doesnt work?
Portfolio Question 2
Write an assembly language program which reads an integer between 1 and 9
from the keyboard and displays that number of consecutive uppercase letters commencing from 'A' all on one new line. If a character outside that range is entered, the program should respond by outputting the character ‘X’ on the same line.
e.g. input : 5 gives the output 5
ABCDE
input : F gives the output FX
