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.
