save_lapw: Yes, I was afraid that would be the answer since the 
save_lapw problem only appeared after I updated my Linux. It seems 
something went sideways there. I will try to find out and be back when 
something surfaces.

HFFnnn: Probably not worth to invest much time. A warning and switching 
to MMI's would be ok with me. Or, if you are interested, I can mail the 
few python lines I use to read plot arrays for gnuplot from case.scf 
files. Perl certainely can do something very similar.

Best regards,

Martin Pieper
