Doc bug: "sort" function referenced in `awk.tex' chapter doesn't exist

[Bill Sommerfeld <sommerfeld@apollo.hp.com>]

awk.tex contains the following example (near the end)

(for-each (lambda (entry) (display (cdr entry)) (newline))          ; Out
          (sort (lambda (x y) (string<? (car x) (car y)))           ; Sort
                (let ((read (field-reader (infix-splitter ":" 7)))) ; In
                  (awk (read) (line fields) ((ans '()))
                    (#t (cons (cons ($ fields 0) line) ans))))))

However, the "sort" function doesn't seem to exist in scsh 0.3.

BTW, I've written one sample program with the awk macro and it seems
to do a good chunk of what I want ... looks good!
