Hi,
sorry for the much delayed reply.Yes, I overlooked the array indices part.

But the problem of @sugs not containing a new list of words each time the sub &tged is executed, is not
really because of @sugs.i.e

@sugs=&suggestcomb($gotfile);

Here @sugs will get overwritten completely each time &suggestcomb returns a new list of words.So the problem
is in &suggestcomb

You are right about the colour change bit too. I've changed the code now to:

sub replace1{

my $chosen1=$opt1;

$t->insert('sel.first',"$chosen1");              
$t->delete('sel.first','sel.last');              
$t->tagConfigure("replaced",-foreground=>"black");

my $r1=$t->search(-forwards,"$chosen1",'end');
$t->tagAdd("replaced","$r1","$r1 wordend");

#print"\nThe start pos of the pattern:";
#print "\n$result";      

}

Got a better way to do the above?Because I don't like the idea of having to search the text.Moreover the colour
still does not change sometimes..?
Thanx :)
