That's a possibility, but take a look at the conversations in recent
threads opened by Bob.  You'll find that he's using this search_text
variable to hold a regexp in an ongoing series of problems he's running
into while writing a script to basically perform an fgrep operation on a
file.  I actually suggested he try out this particular method for
specifying his regexp and assigning it to search_text, so I assumed he
ran into this problem while implementing that. :-)
