I can't be sure what line is line 37 because your program 
formatted "strangely" in my mail-reader, but if {DATA} is not 
defined for that hash (self), it'll create the error you got.

Also, what is "my $hash = %hash" intended to do? Print the 
contents of $hash, and you'll probably be surprised. Perhaps 
you wanted a slash before that %hash to create a reference.
