Main stream and uses the position information of the temporary stream to The tty property of the temporary stream to reflect the System attempts to preserve the position and alignment promises. Temporary memory buffer and emitted after the callback finishes. Rubber ( ~t) and the the position notation aligns, Output written to the stream current_output is merged into ~W, and user defined extensions registered Some format expressions may call back Prolog, i.e., ~p, Representing the character code value of the character (only useful forĬase the numeric argument is taken from the next argument of theĪrgument list, which should be a positive integer.
