Chars   built-in function

The Chars function returns a how many characters remain to be read from an input stream, following the current read position. If the file system uses line separators, the count includes the number of these as well.

Portability note: some implementations are unable to determine how many characters remain and return 1 when an undetermined number of characters remain, and 0 otherwise.

When the default input stream is associated with keyboard input, the number of characters remaining can not be determined.
