string equality without regard to case
Major Section:  PROGRAMMING

For strings str1 and str2, (string-equal str1 str2) is true if and only str1 and str2 are the same except perhaps for the cases of their characters.

The guard on string-equal requires that its arguments are strings consisting of standard characters (see standard-char-listp).

String-equal is a Common Lisp function. See any Common Lisp documentation for more information.
