SYNTAX

(lower-case-p <char> )
        <char>          -       a character expression

DESCRIPTION

The LOWER-CASE-P predicate checks if the <char> expression is a lower case character. If <char> is lower case a T is returned, otherwise a NIL is returned. Lower case characters are 'a' (ASCII decimal value 97) through 'z' (ASCII decimal value 122).

EXAMPLES

(lower-case-p #\a)                      ; returns T
(lower-case-p #\A)                      ; returns NIL
(lower-case-p #\1)                      ; returns NIL
(lower-case-p #\[)                      ; returns NIL
