in thread Clearing anonymous Tk widgets

Other parts of the config file are much more complex than keyword=value. I wasn't going to confuse my objective with all that stuff. My ultimate objective is to find a means of tracking and controlling something for which I have no means of predicting an identifier. If I can write something like

my $name = $frm->.....Button(-command=> sub{delete $hash{$name};$name->destroy()};
that's easy. It's not so easy if I don't know, in advance, how many lines like the above I need nor what to use for the variable name in each case.

    you don't need lines, you need a loop

    Tk::ObjScanner and Tk::WidgetDump use loops, you can use them too
