(nondigit-charlist-p x) recognizes lists where every element satisfies nondigit-char-p.

Definitions and Theorems

Function: nondigit-charlist-p

(defun nondigit-charlist-p (x)
  (declare (xargs :guard t))
  (let ((acl2::__function__ 'nondigit-charlist-p))
    (declare (ignorable acl2::__function__))
    (if (consp x)
        (and (nondigit-char-p (car x))
             (nondigit-charlist-p (cdr x)))
      t)))

Theorem: chars-in-charset-p-of-nondigit-chars
