Without this fix, Netdata files generated by 1.7e are missing a header
field which is required by TSO/E (but not VM or JNET) for receiving
incoming files. All sites are advised to install this fix as MVS users
will not be able to GET files in Netdata format unless it is applied.
Users experiencing problems with release 1.7e servers can try using the
F=PUNCH keyword to get an IEBGENER-style copy of the file, as a temporary
circumvention.
