If I were to convert the following:

Build myksam;rec=-64,64,f,ascii;disc=6400;ksamxl;key=(b,1,15)
Fcopy from=ksamdata;to=myksam

To:

file myksam,new;rec=-64,64,f,ascii;disc=6400;ksamxl;key=(b,1,15);save
Fcopy from=ksamdata;to=*myksam

This would enable the ventilation technique?  If more keys were defined does
this ventilation hold true for each key path?
