Hi Ronald,

thanks for your immediate answer. Could you give some hints about using 
these facilities? Is it sufficient to use 'fortran_storage_order' or do 
I have to build things upon the general system? I've already looked into 
the documentation, but I'm not sure what the right way would be...

Thanx again,
Matthias
