Syntax
- (both-case-p char)
- char - a character expression
returns - T if the character
is alphabetic, NIL otherwise
Description
The 'both-case-p' predicate function checks if the 'char'
expression evaluates to an alphabetic character. If 'char'
evaluates to an alphabetic [either an upper or lower case] character
T is returned, otherwise
NIL is returned. Note that XLISP is limited to ASCII characters, so there is no way to
find out if an Unicode character is 'both-case-p' if the
char-code is greater than
127.
Examples
(both-case-p #\A) => T
(both-case-p #\a) => T
(both-case-p #\1) => NIL
(both-case-p #\[) => NIL
