Hi,
Your code would also work to some extent, I guess. We could put all the text in the Tk window in a scalar
variable, and do a regex match with the string stored in that variable.

Your offset value of '27' would give me the character number of the starting point of the word.But I would
also need the line number if I am to do something further with the word, for example change the color of the word using code like this:

$t->tagConfigure("wrong",-foreground=>"red");    
$t->tagAdd("wrong","$start","$end_pt");

Tk text widget indices are of the form: line no.char no, chars begin at 0, lines begin at 1

i.e. I would need => line no.27

Thanx for the regex bit of code anyway.
:)
