For the other frames you would need to write the numbers to a file.  A 
set of MechSim_Write_Index()/MechSim_Read_Index() macros could be useful 
but is fairly straight away to write.  You can also simply print the 
numbers in the message window using #debug and insert them manually. 
This is not a flaw in the system but completely intentional.  It is the 
only way it can work.
