Monks: I am tryng to understand the code for floor.pl that is part of the standard "widget" application that is part of Perl/Tk. In that file I am seeing constructs such as
<p>
(line 64)
<code>
floor${floor_number} </code>
</p>
and
<p>
$active_floor is defined as a variable and I see reference to:
<code>
$$active_floor
</code>
</p>
Could anypne please shed light on these two cases?
Thanks
