Vocabulary
io

Inputs and outputs

stream

an output stream

Generic word contract
Writes a line terminator. If the stream does buffering, output may not be performed immediately; use stream-flush to force output.

Notes
Most code only works on one stream at a time and should instead use nl; see Default input and output streams.

Errors
Throws an error if the I/O operation fails.
