less-than-or-equal test for strings
Major Section:  ACL2-BUILT-INS

(String>= str1 str2) is non-nil if and only if the string str2 precedes the string str1 lexicographically or the strings are equal. When non-nil, (string>= str1 str2) is the first position (zero-based) at which the strings differ, if they differ, and otherwise is their common length. See string>.

The guard for string>= specifies that its arguments are strings.

String>= is a Common Lisp function. See any Common Lisp documentation for more information.
