The 2105 does not specifically say that either a Write Data or a Write Key
and Data with a 0 length in the CCW byte count will cause an error if inside a
Locate Record Domain, so I think they would work there, but they will cause
a Unit Exception error outside a Locate Record Domain.
A format-0 CCW cannot have a zero data length (except for a TIC). This
is detected in the channel and is documented in the PoPs manual, not the
2105 manual. However, a Format-1 (31-bit) CCW can have a zero data
length. the 2105 manual documents what will happen if the CCW data
length does not match the data length of the existing record (zero for a
a EOF). Very complicated
