Hello again.
This message is to thank Wolfgang for his response on interactive documents that has worked very well. I would now like to put another small question. I prepared a document with a bibliography at the end. To do this I use the modules \usemodule[bib] and \usemodule [bibltx], but since the bibliography is in Spanish, when two or more authors appear, I would replace "and" by "y". With the format ap-fr appears "et", but there is not a *apa-is. HowI can do?
Thanks again.
