Not just that.  MS-DOS is asserting that writing zero bytes to a file
is an operation which isn't needed.

I am aware of "ANS" forths whose WRITE-FILE will truncate/extend
if 0 bytes are written - which is how they implement RESIZE-FILE.

The spec for WRITE-FILE READ-FILE appears to include u1 = 0.
But need it.  I don't recall using such a thing - particularly in a
Standard setting.  ANS could have made it ambiguous as they did
with ACCEPT with little impact.
