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

(line 64) 

floor${floor_number}

[download]

and

$active_floor is defined as a variable and I see reference to: 

$$active_floor

[download]

Could anypne please shed light on these two cases? Thanks
