Process A creates a text file and start writing to it, process A send
the channel to process B, process B want to write more data to it.

B send "ABC\n" to wrapper.

What does the wrapper write to disk?

RFM=STMLF : 0x41 0x42 0x43 0x0A
RFM=VAR : 0x03 0x00 0x41 0x42 0x43 0x00
RFM=VFC : ...
RFM=FIX MRS=512 : ...

And that is just for sequential files. We also got index-sequential
and relative files.

Yes - C IO and RMS IO are not easy to align, but we have RMS whether we 
like it or no.
