If you really need an empty entry, the TTR needs to point to an EOF record. I haven't tried this, but I would try an OPEN for output, a NOTE, set the "last I/O was write" bit in the DCB, and then the STOW (no WRITE/CHECK).
I thought that NOTE was allowed/meaningful only after at least one I/O was issued and all outstanding I/Os were checked. (Doesn't it get its information from the IOB for the previous I/O?) -- gil
