Thank you for helping me solve my problem with the programming.
I tried to compile the corrected program by you, but an error occurred, which said "Warning: Missing newline" and "Error: EOF in comment".
I am happy to know that there's function that is similar to "display ()", which allows me to send strings to it to be displayed in the Hyperterminal. WIth this function, I won't have to program each letter to be displayed, but rather type the whole sentence for display. If you kindly enough to provide me the code??
This is an open question. Is there any function that allows the program to "jump" to certain command in the program. If you notice in my program, I always put "What would you like to do?" after the "if" command. So I wonder whether I can only write those commands once and everytime after the user key-in number "1" or "2", the program will "jump" to diplay that message and continue scanning for the next instruction.
