Hi Hans and Mikael, This is amazing! Mikael's example works for me. I will start using these tools in my project, and I’ll tell you how it goes. It might be a couple weeks, because the physics is also quite challenging. Thank you!

Hi List,
I solved my original problem 2, allowing me to reuse the same \hpos labels in

attached an example by Mikael ... it should work with tonights update

Using this could work
\newcount\SFNum
\global\advance\SFNum\plusone
\the\SFNum
(you now use a (global) lua counter
The code I added is below, with some comments. The complete example file is
attached. The result is two equations.
Each equation was written using the same labels (X,Y,Z), but internally they
have separate sets, (1:X and 2:X, etc.).
The moral of the story for me: Use more Lua.
but ... work local ... so
document.sfnum
etc in order to avoid clashes
Gavin
