to the position where 5 was input and thereby deletes 5.

7.2.3. Error
l
Note that an error occurs in any of the following cases:
1)
If a nonexistent command (i.e., character string) is entered.
(If an entered character string cannot be decoded.)
2)
If data or subscript out of the allowable range is entered.
3)
If a command requiring the password is entered without the password.
l
In any of these cases, the entered character string with a “?” mark is returned as an error message.
For example,
