@ -70,10 +70,14 @@ benefit as @onscreen{Constructor} output, in that printed results are
expressions, but it is more convenient for many kinds of data,
especially data that represents expressions.
The @as-index{@onscreen{write} output} mode corresponds to traditional
Scheme printing via the @scheme[write] procedure.
The @as-index{@onscreen{print} output} mode corresponds to traditional
Scheme printing via the @scheme[print] procedure, which defaults to
@scheme[write]-like printing, as shown in the last column.
The @as-index{@onscreen{current-print} output} mode, when available,
prints results using the value of the @scheme[current-print]
parameter, which allows the programming running in DrScheme to control
its own output format.
DrScheme also sets the @scheme[global-port-print-handler] in order to
customize a few aspects of the printing for all of these modes, namely
printing the symbol @scheme[quote] as a single tick mark (mutatis
mutandis for @scheme[quasiquote], @scheme[unquote], and
@scheme[unquote-splicing]), and to print rational real numbers using a
special @scheme[snip%] object that lets the user choose between
improper fractions, mixed fractions, and repeating decimals.
