        $hash {$thermos [3]} [0];  # enthalpy for fourth thermos value
    $hash {$thermos [7]} [1];  # entropy  for eigth  thermos value.

      thanks again, but I don't really understand what context I can use this in  $hash {$thermos[3]}[0];! If i try to print it - nothing happens. If a print it within quotes, it thinks $hash is seperate to %hash and complains! How can I write a test; e.g. if $thermos[3] is equal to $some_value print the corresponding values $enthalpy and $entropy to $thermos[3]. thanks for your patience

        I strongly urge you to read some manuals. You can't expect us to spoon feed you every single line of your program.
