Dear Thomas, that works like a charm. Thank you indeed!

Dear Oliver, Using .nf is also important but I think it is not clear from the manual (either info or groff(7)) that this is needed, if only for getting rid of the 'cant break line' errors. I think this achieves the desired result: .nf .ta 2mR T 2mR .nr x 1 .nr y 1 .nr p 0 .while (\n[x] <= 12) \{\ .while (\n[y] <= 12) \{\ .nr p \n[x]*\n[y] .nr y +1 \n[p] \c .\} .br .nr x +1 .nr y 1 .\} As you can see I added a tab character before and after \n[p] to achieve this. The previous example did not work because I did not remember that you should begin with a tab character. For this kind of thing I tend to rely on the Unix Text Processing book more and more. A very similar example of what you are trying to achieve is described on page 66 (4. nroff and troff > Page Layout > Setting tabs). You can get this book here: http://chuzzlewit.co.uk/utp_book-1.1.pdf
This book has long been known to me, but unfortunately I never consulted the mentioned section before.
Also there is no need to specify the steps x or y should take if auto incremented because we don't use that here. The step value is interesting if you use \n+[x] or \n+[y] somewhere in your code. There are more examples in section 5.6.3 of the info manual.
You are right, the increment steps for x and y are not needed. They were left-overs from earlier experiments with steps and counters, I left them in the code as they did no harm. Thank you again! Best regards, Oliver. -- Dr. Oliver Corff Mail:oliver.co...@email.de
