Language Help

I have been using the guide as well as other members' screeen to teach myself how to create screens. However, i cannot figure out the $Var parameters at the top of the results.

$VAR1 = {
'org_cagrgsd' => '3.53846153846154',
'cagrwarninglevel' => '3000',
'org_end' => '2008-05-02',
'org_cagr' => '184',
'src' => 'Define {LowPS}

What do these parameters do?

Thank you for the help!
