## 1.1. Special Symbols [sec_1-4-1-3]

The final delimiter of an interactive stream:

UNIX
  type Control+D at the beginning of a line
Win32
  type Control+Z, followed by Return

This final delimiter is never actually seen by programs; no need to test for #\^D or #\^Z - use `READ-CHAR-NO-HANG` to check for `end-of-stream`. Calling `CLEAR-INPUT` on the stream removes the `end-of-stream` state, thus making it available for further input.

A newline character can be entered by the user by pressing the Newline key or, on the numeric keypad, the Enter key.
