<question heading="Count words of the selected text with ooRexx">How to count the words of selected text?
</question>

<answer>
<p>First get the selected text. Now iterate trough the selection parts and</p>
<p>get each of them as a string. Use this string with the &quot;WORDS()&quot;</p>
<p>function of ooRexx to count its words. Finally sum up all counts.</p>
<p>For further details see http://wi.wu-wien.ac.at/rgf/diplomarbeiten/BakkStuff/2008/200809_Frysak/200809_Frysak_Automating_OOo_ooRexx_Nutshells.pdf.</p>

   -- get context

   size = x_IndexAccess~getCount()

   -- iterate trough the selections and retrieve the selected strings
   -- count the words within the strings by using ooRexx builtin function WORDS
   do counter = 1 to size
