Restrictions
If a NULL string is given (txt="") then the last string
given is used. This saves finding the words again.
If m > n wrd will be a string of words from word n to
word m. If no m is given wrd will be a single word.
n<0 returns text starting at word abs(n) to string end
If n is out of range then a null string is returned.
