Yep for the second argument to the matchText() function, you need to  
construct the regular expression so that it contains "^" as the first  
character, followed by the contents of your variable, followed by the  
"$" character.  In RR you can concatenate strings with the "&"  
operator, so you could do something like this for your second argument:

"^ & tword & "$"

For your first argument, you would just your tword1 by itself.  If  
you put it in quotes like in your example, you are matching the  
literal string "tword1".
