Thanks a lot, Tim. I was sure that freeze/thaw is like store/retrieve with an exception that the data is stored in memory instead of in the file and I can get the data inside the child process just by thawing it. I'll have to use store/retrieve functions because I don't have experience in converting scripts into modules. Well, maybe it's a good time to start gaining this experience. Again, many thanks.
