\section*{Preface}
\pdfbookmark[1]{Preface}{preface} EuroForth is an annual conference on
the Forth programming language, stack machines, and related topics,
and has been held since 1985.  The 39th EuroForth finds us in Rome
where we finally meet again in person, after three years of online
meetings.  Information on earlier conferences can be found at the
EuroForth home page (\url{http://www.euroforth.org/}).

Since 1994, EuroForth has a refereed and a non-refereed track.  This
year there have been no submissions to the refereed track.
Nevertheless, I want to thank the program committee for their
willingness to review papers.

\comment{, which was
accepted (100\% acceptance rate).  For more meaningful statistics, I
include the numbers since 2006: 30 submissions, 22 accepts, 73\%
acceptance rate.  This year the only submission was authored by the
program chair; Ulrich Hoffmann served as secondary chair and organized
the reviewing and the final decision for that paper.  The reviews of
all papers are anonymous to the author: The paper was reviewed and the
final decision taken without involving the author.  I thank the
program committee for their paper reviews.}

Several papers \comment{and slide handouts} were submitted to the
non-refereed track in time to be included in the printed proceedings.
Late papers as well as slides and links to videos will be included in
the final proceedings (\url{http://www.euroforth.org/ef23/papers/}).
I thank the authors for their papers.

\comment{
In addition to the papers and presentation handouts available before
the conference, these online proceedings also contain \comment{papers
  and} presentation handouts that were provided at or after the
conference.  \comment{Also, some of the papers included in the printed
  proceedings were updated for these online proceedings.}  I thank the
authors for their papers and slide handouts.

You can find these proceedings, as well as the individual papers and
slides, and (when they become available) links to the presentation
videos on \url{http://www.euroforth.org/ef22/papers/}.}

Workshops and social events complement the program.  This year's
EuroForth has been organized by Gerald Wodni.
