Dear All, while tinkering Re^3: How to declare variables per loop I faced a new problem.
The parameter hash which should be used further to generate a gnuplot command grows up to a huge thing since there are ca. 20 topics (as THIS, THAT etc.) with up to 12 indicators. 
my %module = (
    THIS => 
    {
      name => q{This Great Evaluation},
      indicator =>    {
        '01' => {
            ind => q{First},
            legende => q{bottom},
            yscala => q{[:100]},
            },
        '04' => {
            ind => q{Fourth},
            legende => q{bottom},
            yscala => q{[:100]},
            },
        
        '06' => {
            ind => q{Sixth},
            legende => q{bottom},
            yscala => q{[:100]},
            },
        '07' => {
            ind => q{Seventh},
            legende => q{bottom},
            yscala => q{[:100]},
            },    
        '08' => {
            ind => q{Eighth},
            legende => q{bottom},
            yscala => q{[:100]},
            },    
        '11' => {
            ind => q{Eleventh},
            legende => q{bottom},
            yscala => q{[:100]},
            },
        '14' => {
            ind => q{Fourteenth},
            legende => q{top},
            yscala => q{[0:]},
            },
        '15' => {
            ind => q{Fifteenth},
            legende => q{top},
            yscala => q{[0:]},
            },    
        '16' => {
            ind => q{Sixteenth},
            legende => q{top},
            yscala => q{[0:]},
            },
                
      },
    },
    ,
);

I thought if it were possible to save this hash in a separate file and access it from the main file later.
In fact I tried to save the file as, say, parameter.pm and typed use lib (..Pfad..); and use parameter.pm; but I get an error.
Could you please give me an advice?
Many thanks.
