Writing Characters

put(N) writes N to the current output stream or put(Stream, N) writes N to a specified one, Stream. N should be a legal ASCII character code or an integer expression.

If N evaluates to an integer, the least significant 8 bits are written.

The character is not necessarily printed immediately; they may be flushed if the buffer is full. See ref-iou-sfh-flu.
