5 years ago I modified jaaa (version 0.6.0) to be able to store 
measured data into a file. You could launch it with an additional 
flag "-f Filename" and than anytime you freeze the display the data 
gets written into the same file so you have to rename that file 
between different freezes.

Those patches never found the way into Fon's version (he was in the 
last stage of an rewrite and thus the patches did not fit with his 
actual version). He obviously does not have any need for storing the 
measured data.

I've done something similar (more quick & dirty) for japa (same 
version) that is still available.

If you are interested please send me a private note. I can send you 
executables as well as the patched sources for jaaa and japa.
