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.
