Hi, thanks a lot for the reply
actually I am working with text in another language,
not English text.I gave that example in my post just to
state the problem(or so I thought).I had not at all tested
with english text.

In fact my code as well works with the english text file:

x.txt

try **until **you **succeed
[download]

but strangely does not work for my text file which looks
like this, if the display is set to an english font:

y.txt

]]»  **]X»]»   **]Eõ]»    ]]»»
[download]

In this case only the first character next to the 2nd
asterisk is printed:

$result: 1.4
$start: 1.6

The word:
]
[download]

I need the whole word to be printed that is:

]X»]»
[download]

What I then need to do is change the font color of
the word so that it stands out in the widget window,
and delete the **'s.
I need to present the text in the Tk widget as a user
interface.The user clicks a button, certain words get
marked by the asterisks.But instead of the asterisks,
I now want to change the font color of the words instead.

I'm not sure how I can search within a widget window
using regexps.

here's my actual code, with a whole lot of it not relevant
to this question omitted.

#!/usr/local/bin/perl -w

use Tk;
#use strict;                

our($filename, $info);                 #Variables to be used in the su
+bs &load_file and &save_file.  
                                       #$filename stores the file name
+ typed by the user in the entry widget of the main window.
                                       #$info stores the text message 
+displayed at the bottom of the main window.
                                       
my $mw = MainWindow->new;              # Main window.

What is the alternative to using the 'wordend' index? That does not seem to work here. Thanx
