Generally there are two ways of doing text input: fixed-width and
variable-width. In fixed-width form, the user must type exactly the
number of digits *you* want (no more, no less) but there is no need
for an extra character. This is really only useful when reading from a
file instead of the keyboard. In variable-width form, the user types
as many characters as *they* want, but they also have to insert a
terminating character. Usually, that character is Line Feed (produced
with the ENTER key). If that's what you want, you may want to call
Ada.Text_IO.Get_Line then traverse the resulting string looking for
digits.
