(the package variable (%items above) is not available).

It is not, because %items is declared as a my variable and thus available only in the the package itself, not in the main package.

If you have to access it from main, you either have to fully qualify it as %items::items, or provide methods to access it (exporting it, providing accessors or a method which returns a reference to it, etc), but it's hard to say what's best without knowing the whole scenario.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'

`my` variables are local to the lexical scope in which they are declared, and can not be accessed outside that scope. If you want to access `%items` outside the file in which it is declared, you need to specify `our %items`, not `my %items`. Then you can access it by its fully-qualified name. That is, if it is declared in package `Foo` you say (e.g.) `$Foo::items{Dent} = 'Arthur';`. In an ideal world the OP would not be mucking around with global variables, but this is not an ideal world.
