1.1     ! root        1: #print
        !             2: Now you should understand the special characters ^H and @:
        !             3: 
        !             4:    ^H     cancels the previous character typed (called control-h)
        !             5:     @     cancels the line being typed and puts you on a new line
        !             6: 
        !             7: ^H is typed by holding down the CTRL (for control) key and pressing
        !             8: the letter 'h'.  The reason that there are the two characters
        !             9: '^' and 'H' to represent one special character is that ^H usually
        !            10: will not print on the screen.
        !            11: 
        !            12: If you make a typing mistake, you can use ^H and @ to correct it
        !            13: before you finish the line and the computer won't ever know about it.
        !            14: For example, what will the computer really receive if you type
        !            15: 
        !            16: st^Hhe@thf^He
        !            17: 
        !            18: at it?  Figure this out in your head and reply "answer WORD" where
        !            19: WORD is the word as it will be interpreted, and don't forget RETURN.
        !            20: For example, if you think it will get "dog", type
        !            21: 
        !            22: answer dog
        !            23: 
        !            24: #copyin
        !            25: #user
        !            26: #uncopyin
        !            27: #match the
        !            28: #bad answerthe
        !            29: Leave a space between "answer" and "the".
        !            30: #log
