As the person who nagged Enrico to make \jobname easily accessible in 
preview files, I am 7 years older now, have more experience with expl3 
(the programming language of LaTeX3) and have superseded the calculyx 
package which was available on the LyX wiki with the numerica package on 
CTAN. This is a standalone LaTeX package not specifically tailored for 
use with LyX as calculyx was. I have no objection if you decide to 
change the behaviour of \jobname in previews.
