23.2.3 make-dispatch-macro-character [Function]

make-dispatch-macro-character char &optional non-terminating-p readtable ⇒ t

Arguments and Values::

char—a character.

non-terminating-p—a generalized boolean. The default is false.

readtable—a readtable. The default is the current readtable.

Description::

make-dispatch-macro-character makes char be a dispatching macro character in readtable.

Initially, every character in the dispatch table associated with the char has an associated function that signals an error of type reader-error.

If non-terminating-p is true, the dispatching macro character is made a non-terminating macro character; if non-terminating-p is false, the dispatching macro character is made a terminating macro character.

Examples::

 (get-macro-character #\{) ⇒  NIL, false
 (make-dispatch-macro-character #\{) ⇒  T
 (not (get-macro-character #\{)) ⇒  false

The readtable is altered.
