[femm] FEMM files' format and other

[Sincro <tecnico@xxxxxxxxx>]

My company makes electrical machinery.
I have written my own c++ subroutines to read and write femm's input and output files. This is useful for interfacing directly my calculation programs with femm kernel. My library works for 2.1 version files. Shall I expect file format changes in version 2.1a or next versions?
If so, may I have also a description of the new formats? (I have understood them one time, but it is not nice work)
I would like to run triangle.exe and fkern.exe from my programs, what command line must I invoke?
Is it possible (or will it be in a future version) to run femmview.exe from command line asking for some operation and having the result on a file? (I think of somthing like"femmview.exe -AJintegral inputfile outputfile", where inputfile contains the line and outputfiles the result; at the moment I do it in my subroutines).
I have seen that currents defined as point properties are not taken into account in AJ integral (and perhaps in some other calculation); must I always use block properties in order to have a correct result in AJ integral?

thank you.
