Charin   built-in function

The Charin function returns a sequence of characters from an input stream, at the current read position.

If there are insufficient characters available, the result will contain only the characters which remain .. AND the NOTREADY condition is raised.

When the default input stream is associated with keyboard input, the program will wait until the user types sufficient characters at the keyboard. The user may have difficulty identifying the program is waiting for input.

When the length argument is omitted, and the start arguments is present the current read position of the stream is set to the start position, and the empty string is returned.
