I thought a count of zero was prohibited in a CCW. (But there may be
other ways.)

You are correct. But a DASD Format Write requires a COUNT field of 8
bytes. The count field may, in turn, have a value of zero for the data
length, thus writing a EOF mark.
If a Update Write doesn't have the correct size, you'll get a Unit Check
or Unit Exception (I forget which) with Incorrect Length set..
