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 comparisons.  To check whether two strings are anagrams of each other
       (i.e., they contain the same characters, but in different order), compare 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.
