Working with REXX (strings and words) is trivial.
<lang rexx>s='rosetta code phrase reversal'
Line 576 ⟶ 577:
each word reversed : attesor edoc esarhp lasrever
word-order reversed : reversal phrase code rosetta</pre>
===version 2===
<lang rexx>/*REXX pgm reverses words and/or letters in a string in various ways. */
i=; p=; parse arg $; if $='' then $="rosetta code phrase reversal"
do j=1 for words($); _=word($,j)
i=i reverse(_) ; p=_ p
end /*j*/
say ' the original phrase used: ' $
say ' original phrase reversed: ' reverse($)
say 'reversed individual words: ' strip(i)
say 'reversed words in phrases: ' p /*stick a fork in it, we're done.*/</lang>
'''output''' when using the default string:
<pre>
the original phrase used: rosetta code phrase reversal
original phrase reversed: lasrever esarhp edoc attesor
reversed individual words: attesor edoc esarhp lasrever
reversed words in phrases: reversal phrase code rosetta
</pre>
