Notes:
Overview:
display
.
(display val)
displays a value,
eliminating the quotation marks from around strings.
(newline)
procedure that
starts a new line of output.
write
,
that works a lot like display
except that it also
displays quotation marks around strings and displays characters
with the #\
.
write-char
, only works with
characters.
read
, which
reads one Scheme value, skipping whitespace as appropriate.
read-char
, which reads a single character for input.
read
is an interesting procedure. In many cases, it will
continue to read for more than one line.

Disclaimer:
I usually create these pages on the fly
, which means that I rarely
proofread them and they may contain bad grammar and incorrect details.
It also means that I tend to update them regularly (see the history for
more details). Feel free to contact me with any suggestions for changes.
