====== Function MAKE-DISPATCH-MACRO-CHARACTER ====== ====Syntax==== * **make-dispatch-macro-character** //char// ''&optional'' //non-terminating-p// //readtable// → **[[CL:Constant Variables:t]]** ====Arguments and Values==== * //char// - a //[[CL:Glossary:character]]//. * //non-terminating-p// - a //[[CL:Glossary:generalized boolean]]//. The default is //[[CL:Glossary:false]]//. * //readtable// - a //[[CL:Glossary:readtable]]//. The default is the //[[CL:Glossary:current readtable]]//. ====Description==== **make-dispatch-macro-character** makes //char// be a //[[CL:Glossary:dispatching macro character]]// in //readtable//. Initially, every //[[CL:Glossary:character]]// in the dispatch table associated with the //char// has an associated function that signals an error of type **[[CL:Types:reader-error]]**. If //non-terminating-p// is //[[CL:Glossary:true]]//, the //[[CL:Glossary:dispatching macro character]]// is made a //[[CL:Glossary:non-terminating]]// //[[CL:Glossary:macro character]]//; if //non-terminating-p// is //[[CL:Glossary:false]]//, the //[[CL:Glossary:dispatching macro character]]// is made a //[[CL:Glossary:terminating]]// //[[CL:Glossary:macro character]]//. ====Examples==== <blockquote> (get-macro-character #\{) → NIL, //[[CL:Glossary:false]]// (make-dispatch-macro-character #\{) → T (not (get-macro-character #\{)) → //[[CL:Glossary:false]]// </blockquote> ====Side Effects==== The //readtable// is altered. ====Affected By==== None. ====Exceptional Situations==== None. ====See Also==== * **[[CL:Variables:star-readtable-star|Variable *READTABLE*]]** * **[[CL:Functions:set-dispatch-macro-character|Function SET-DISPATCH-MACRO-CHARACTER]]** ====Notes==== None. \issue{ARGUMENTS-UNDERSPECIFIED:SPECIFY}
