Hi all... I have been programming a world clock using Perl/Tk. I am fairly new to Perl (and more so to Tk). I am stuck at one point when I have to click a button and this leads to a subroutine. The first thing in that subroutine is that every existing slave, including the calling button, should be unpacked. I originally made all these widgets available to the whole script, so that I did not need to pass them to the subroutine, but now I am trying to prune my code so that so that variable scope is as limited as possible, and that's why I need to pass these widgets (variables) to a separate subroutine. My code is something like this...

{##### block of code #####
my $button2 = $frame2->Button(-text => "Label",
-command => \&subroutine2($label2, $frame2, $button1, $button2))->pack
+();
##### block of code ends here #####
}

sub subroutine2{
foreach @_{
packForget $_;
}
##### rest of subroutine #####
}

I don't know if this is even a legal call. But this does not seem to work even if I do not pass $button2. Can you please suggest a way out of this? Thanks a lot for your help.
