Sucks.

It should contain data specific to every $lang/$kurz pair (whatever $kurz is -
I don't speak German, and one should use English identifiers in one's code.).
The keys would be either $lang or $kurz (whatever you prefer to iterate on)
and you would populate the values of the hash (which could be a hash
reference, but should preferably be an object of a certain class) with the
variables specific to the $lang/$kurz pair like you do now with varvarname.

"NoraSqlObject" is the class name of the objects you would use as the values
of the hash that holds the data for all $lang/$kurz. It could be called
differently. To learn more about objects see:
