Dear PerlMonk replying me :

• My problem is the storage of a record in one datatype which I can send to another application using TCP/IP. My record can contain binary fields of each max. 20 MB. The other applicatio must be abel to reconstruct the record or at least extract the fields from it. That other application is running on a different computer and the transfer of the data will be by using sockets / tcp/ip.
