Hi Hans,

Thank you for your reply.
It took me a while to make your code operational in the way I need it.
For the new example you gave is still an "integral file". My project, like most book-projects, I guess, is modular with a master file Project.tex, into which everything else, setups, .bbl's, front- and backmatter, the various chapters are input. Though strictly speaking it would not be impossible to add some 1000 lines of index entries before \startproject, it would not be especially handy, and I cannot believe that it would be the proper ConTeXt-way to do it.

I found that when I split your code, transferred the top part to a new file, which I named "IndexItems", and input that into the other half, the text proper, it works. But when I add another file with indexentries, for instance "indexitemsnames", then only one of them, the one at the top is used. 
So it seems that the whole collection of index items must be in one file.
Is that the only possibility or are there ways to enable the use of several collections of index items?

Best regards, 
Robert
