FLUKA: user defined magnetic field

[Lev Chekhtman <Lev.Chekhtman@cern.ch>]

Hello, I am using magnetic field defined by MGNFLD routine (using zeros
for Bx,By, Bz in MGNFIELD option). At runtime I get a lot of messages in
the .err file that look like:

MAGNEW, TXYZ: n.nnn
U,V,W  n.nnn   n.nnn   n.nnn


where n.nnn are some numbers.
Why do I get these messages? What do they mean? Cheers, Lev.
