- open-output-ropeprocedure
open-output-rope returns a port to which output can be written and accumulated, until returned as a rope with get-output-rope.
In reality, open-output-rope and open-output-string are the same. Construction of the rope returned by get-output-rope is delayed until that procedure is called, so get-output-rope may be used to return a rope from the accumulated output of ports created by either open-output-rope or open-output-string.
