Hi Olaf,

Thanks again.

This looks very interesting. I assume I would have to start all 
processes in some special way to get the file number. Is there any way 
that would work for two unrelated octave processes running on the same 
machine under the same user? You mention a non-windows machine - working 
only for linux? Unfortunately that would be a problem for me. While I 
develop everything in linux, my project will have to support windows too.

Great option, the database package is easy to install on any platform. I 
will investigate if the fsave/fload option is not available. Please is 
there any safe byte/byte combination to use as a separator between each 
serialized block?

Thanks a lot again,

Pavel.
