[Yazlist] yaz-marcdump option to convert MARC-8 to "combined UTF-8"

Thank you for that Larry. I can now construct the command line to
theoretically convert the MARCXML back to ISO2709, but when I tried with
my 3 record file, it failed.

My commands are:-

  yaz-marcdump -f MARC-8 -t UTF-8 -o marcxml -l 9=97 !src! >>!xml!
  yaz-marcdump -v -i marcxml -o marc !xml! >!dst! 2>>!rpt!

Looking at the "XML", it is not XML because it does not have an
encapsulating tag, instead it repeats the 'record' tag. Looking at the
Schema* it would appear that the file should be enclosed in

So, I added commands to encapsulate the file accordingly:-
  echo ^<collection^>>!xml!
  yaz-marcdump -f MARC-8 -t UTF-8 -o marcxml -l 9=97 !src! >>!xml!
  echo ^</collection^>>!xml!

but all I get from yaz-marcdump is:
	yaz_marc_read_xml failed

It would appear that yaz-marcdump does not write or read the
<collection> tag but without it I get, quite rightly:-
	<filename>:<line>: parser error : Extra content at the end of
the document
	<record xmlns="http://www.loc.gov/MARC21/slim">

Can anyone offer advice ?

Thanks very much in advance and Happy Holidays to everybody.

I have a meeting in a few minutes, but attached is a more recent version
of the yaz-marcdump man page.  This will help to answer your question
about option -l (in the case you cited -- changing
Leader/09 to an "a" (decimal 97).  You will also see the possible values
for option -o.

Hope that's somewhat helpful.
