5.1.2 User Input
You can enter a character string on your input line (shown by the >
symbol). It is terminated and submitted for evaluation when you enter a
Carriage Return or Line Feed (usually the
RETURN,
|
, or ENTER key).
While entering a line you may use the following editing facilities:
Delete a Character
When you enter a Delete (
DEL) or Backspace (BS) character, the last
character that you entered is erased.
Delete a Line
When you enter a Control-U (
^U) or a Control-X (^X) character is entered,
the line is erased ready for you to re-enter.
Repeat a Line
When you enter a Control-R (
^R) is entered, your previous entry is
repeated.
Illegal Characters
If you try to enter any control character except those listed above it will not
appear on the line. Instead a
^G (bell character) is returned and your entry
ignored. This also occurs if the current input line is too full of characters.
