The only thing that is consistent across all of the guest OSes is that it tells the SIMH file server how many octets are going to be written to disk (the guest OS tool has to convert the actual word size into octets so that the data file is just a stream of bytes)

Well, the goal was to transfers files into and out of the guest system. 
If you want to transfer files into the guest system, you cannot really 
expect the guest system to create the information...
