Hi,

thanks for your sending a modified version of vec2old_lapw.
although I have not try it now, it seems to work well.
I'll try it tomorrow. if there is any problem, I'll get back to you.

With best regards,
Tomo

Try the attached version of vec2old_lapw, which is from the next release.

Make sure you execute      x lapw2 -p -qtl
on the same machines and you have again defined the SCRATCH variable.
