Well, we're back to defining "did not work".  We understand that the
symptom was that the header record, for whatever reason, did not end
up in the export file.  The question is "why".  What "didn't work",
which caused the header record to not end up there?  Are you sure that
you actually executed the EXPORT twice?  Maybe it's not that the header
record got overwritten.  Maybe it never got written in the first place.

It may "work" with two separate exports, but it's probably a lot more
work than is necessary, and overly complicated.  A single export,
executed twice, is clean and simple.

With a single EXPORT command, executed twice, there is no need for any
WRITE or CLOSE statements.  (Unless you are completely finished with the
export, and want to continue doing other things, while making the export
file available to other programs.  In that case, you should CLOSE it
after the last record has been exported.)

Without having more than just bits and pieces of the code, there's no way
for anyone to know.
