[ Character I/O | Reference Manual | Alphabetic Index ]


Reads the next character or byte from the current input stream
Variable or integer.


Takes the next character from the current input stream, and unifies its integer character code with Code. The range of possible values depends on the stream's text encoding, or is 0 to 255 for binary streams.

Character codes for the non-printable characters (i.e. control characters) are treated like normal characters.

On end-of-file, -1 is returned (via the default handler for event 190).

(5) type error

(190) end of file reached
