Changing the properties of different widgets in the "window", like
enabling a button, changing text, etc.

Yes, almost. I need to get to widgets from the built in code editor. If
you look at the code below:

my $t = Prima::Timer -> create(
             timeout => 250,
             onTick => sub {
 
my $mode = getMode('a');
chomp($mode);
        if ($mode eq "USB") {
                   $self->set( enabled => 1 );
                   print "Tick\n";
        } elsif ($mode eq "LSB") {
                   $self->set( enabled => 0 );
                   print "Tock\n";
        }
    },
);
$t->start; (I realize $self in the code window wouldn't work)

If I place this code into say, onCreate event in the label widget
"lblUSB" it works perfect, the current widget object appears to be in
in $self. However if I place this same code into the "code editor", it
executes (the tick tock's), but I am unable to access the lblUSB, no
matter what name I use. To make things more confusing to me:

>your Form1, $form->lblUSB should be what you need.

I cannot find anywhere in the .frm file an object name that I can use!
I guess I am really confused where all the name-spaces reside.

Thanks for all you help so far,
Tim
