Dear Matthias

what do you mean by large?

Probably you could write your own simple reading routine for this problem.

Probably you could use the `where` function to get returned the indexes of
the submitted code. This index vector could be used to separate a part of
the structure
Afterwards you use `sort` for the parameter to get a second index vetor.
