====== Function ALPHA-CHAR-P ====== ====Syntax==== * **alpha-char-p** //character// → //generalized-boolean// ====Arguments and Values==== * //character// - a //[[CL:Glossary:character]]//. * //generalized-boolean// - a //[[CL:Glossary:generalized boolean]]//. ====Description==== Returns true if //character// is an //[[CL:Glossary:alphabetic]]// //[[CL:Glossary:character]]//; otherwise, returns false. ====Examples==== <blockquote> (alpha-char-p #\a) <r>//[[CL:Glossary:true]]// </r> (alpha-char-p #\5) <r>//[[CL:Glossary:false]]// </r> (alpha-char-p #\Newline) <r>//[[CL:Glossary:false]]// </r> ;; This next example presupposes an implementation in which #\alfa is a defined character. (alpha-char-p #\alfa) <r>//[[CL:Glossary:implementation-dependent]]//</r> </blockquote> ====Affected By==== None. (In particular, the results of this predicate are independent of any special syntax which might have been enabled in the //[[CL:Glossary:current readtable]]//.) ====Exceptional Situations==== Should signal an error of type type-error if //character// is not a //[[CL:Glossary:character]]//. ====See Also==== **[[CL:Functions:alphanumericp|Function ALPHANUMERICP]]**, {\secref\ImplementationDefinedScripts} ====Notes==== None.
