 I ran examples/extended/electromagnetic/TestEm1 with the following macro :

 #
 # Macro file for "TestEm1.cc"
 #
 /control/verbose 2
 /run/verbose 2
 #
 /testem/det/setMat Lead
 /testem/det/setSize 1.3 m
 #
 /run/initialize
 #
 /testem/gun/setDefault
 /gun/particle mu+
 /gun/energy 4.26 MeV
 #
 /process/inactivate Decay
 #
 /tracking/verbose 1
 #
 /run/beamOn 1

 The output is :

 ---> Begin of Event: 0
