Thanks to all who responded to this.
I have found a workable solution (for me).
Of the various solutions suggested,
the best (for me) seems to be Grep.
(downloaded from http://www.wingrep.com/)
As far as I can see, it is not possible to configure
the search type within Windows XP as it is with Vista.
The free versions of Ultra-Edit & WinEdt are a time-limited.
(unlike Grep, which merely suggests you register.)
-find- from a DOS prompt gives too much text
(including files without the text searched for)
So thanks in particular to Al Feiveson's son.
