Martin,
I am writing this in English, since you may need to forward it.
It has been called to my attention that in the May issue of the UT-Magazine, Spanish edition, my article (primary keys) is cut-off at the end. Comparing the article with the English version (which seems to be complete), the last three lines of function SerialNumber() are missing, as well as the entire function to generate GUIDs, and the author's biography at the end.
I suspect that perhaps it was incorrectly assumed that the Spanish edition would have the same number of pages as the English edition.
Regards, Hilmar.
