Will look in it.

In my installation this directory doesn't have fmt files. In any case I
will look in it.

Yes, that's right, but I forgot that this is octal number, therefore
032212676346=3526065382=210·256^{3}+43·256^{2}+124·256^{1}+230·256^{0},
so 210,43,124,230 are written in file as D2, 2B, 7C, E6 (which I found
in VF file :).
