+@title[#:tag "parameterize"]{Dynamic Binding: @scheme[parameterize]}
+
+The @scheme[parameterize] form supports a kind of dynamic binding that
+is useful for adjusting defaults or passing extra arguments through
+layers of function calls. The settings that are adjusted by a
+@scheme[parameterize] form are called @deftech{parameters}.
+
+@margin-note{The term ``parameter'' is sometimes used to refer to the
+             arguments of a function, but ``parameter'' in PLT Scheme
+             has the more specific meaning described here.}
+
+@specform[(parameterize ([parameter-expr value-expr] ...)
+            body ...+)]
+
+The result of a @scheme[parameterize] form is the result of the last
+@scheme[_body] expression. While the @scheme[_body] expressions are
+evaluated, the parameter produced by each @scheme[_parameter-expr] is
+set to the result of the corresponding @scheme[_value-expr].
+
+Many parameters are built in. For example, the
+@scheme[error-print-width] parameter controls how many characters of a
+value are printed in an error message (in case the printed form of the
+value is very large):
+
+@interaction[
+(parameterize ([error-print-width 10]) 
+  (car (expt 10 1024)))
+(parameterize ([error-print-width 5])
+  (car (expt 10 1024)))
+]
+
+The @scheme[error-print-width] parameter acts like a kind of default
+argument to the function that formats error messages. This
+parameter-based argument can be configured far from the actual call to
+the error-formatting function, which in this case is called deep
+within the implementation of @scheme[car].
+
+The @scheme[parameterize] form adjusts the value of a parameter only
+while evaluating its body expressions. After the body produces a
+value, the parameter reverts to its previous value. If control escapes
+from the body due to an exception, as in the above example, then the
+parameter value is restored in that case, too. Finally, parameter
+values are thread-specific, so that multiple threads do not interfere
+with each others' settings.
+
+Use @scheme[make-parameter] to create a new parameter that works with
+@scheme[parameterize]. The argument to @scheme[make-parameter] is the
+value of the parameter when it is not otherwise set by
+@scheme[parameterize]. To access the current value of the parameter,
+call it like a function.
+
+@interaction[
+(define favorite-flavor (make-parameter 'chocolate))
+(favorite-flavor)
+(define (scoop)
+  `(scoop of ,(favorite-flavor)))
+(define (ice-cream n)
+  (list (scoop) (scoop) (scoop)))
+(parameterize ([favorite-flavor 'strawberry])
+  (ice-cream 3))
+(ice-cream 3)
+]
