NAME
       stranaxfrm - make a string into canonical form for anagram comparison

SYNOPSIS
       #include <publib.h>
       char *stranaxfrm(char *str);

DESCRIPTION
       stranaxfrm  transforms  a string into a canonical form for anagram com‐
       parisons.  To check whether two strings	are  anagrams  of  each	 other
       (i.e.,  they contain the same characters, but in different order), com‐
       pare their canonical forms.  The canonical  form	 merely	 has  all  the
       characters in the string sorted into ascending order.

       To  write  a  program  to find anagrams, first convert a word list into
       canonical order, then look up words in that version of the word list by
       transforming them also to canonical order.

RETURN VALUE
       stranaxfrm returns its argument.

BUGS
       This function is of a whimsical nature.
