Isn't there a new version of tex coming (dek posted some fixes)? In that case, one can use that version number since the moment that those fixes are in the new distribution sync with the ifeof18 extension.

And how do you check the version of the TeX engine in (non-e)TeX? Best regards Martin -- Martin Schröder, MS@ArtCom-GmbH.DE ArtCom GmbH, Lise-Meitner-Str 5, 28359 Bremen, Germany Voice +49 421 20419-44 / Fax +49 421 20419-10

No, LaTeX does not know, which TeX is used.
also, you can maybe use a latex version number for testing
Not reliable. For example, my tex is much older than my LaTeX
installation.

in that case, why not use the latex version as per tex live 8 (an ifeof18 test macro extension can wait till then i suppose) Hans ------------------------------------------------------------------------- Hans Hagen | PRAGMA ADE | pragma@wxs.nl Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: +31 (0)38 477 53 69 | fax: +31 (0)38 477 53 74 | www.pragma-ade.com ------------------------------------------------------------------------- information: http://www.pragma-ade.com/roadmap.pdf documentation: http://www.pragma-ade.com/showcase.pdf -------------------------------------------------------------------------

I have different TeX installations (useful sometimes for testing with
older versions, for example). Thus I want to say, that LaTeX can
be updated independently from the TeX program. And because of the
stable nature of standard TeX and the Error during LaTeX format
generation this will be often the case.
Yours sincerely
