I have two minor questions about the Revised^3 Report of Scheme.
1) The report mentions two procedures (close-input-port <port>) and
(close-output-port <port>). I don't see why it is necessary to
have two procedures to close ports. Wouldn't it be sufficient
to have something like "close-port" that can be applied to both
types of ports?
2) What is the exact difference between (write-char <char>) and
(display <char>)? "write-char" seems to be redundant. Is "display"
supposed to terminate its output by a space or newline or something
I'm sorry if the answers are obvious; I'm relatively new to Scheme.
