READCHAR
RC
reads a single character from the read stream and outputs that
character as a word. If the read stream is a file, and the end of
file is reached, READCHAR outputs the empty list (not the empty
word). If the read stream is the keyboard, echoing is turned off
when READCHAR is invoked, and remains off until READLIST or READWORD
is invoked or a Logo prompt is printed. Backslash, vertical bar,
and tilde characters have no special meaning in this context.
