Richard,
One way to share data between Jython classes is to use sensors for states and memory variables for values.
If you really want to share the data within the Jython context, you have to use the "global" option. ?When a variable is modified within a class, the local variable will be modified. ?This will not be visible to other classes. ?If the first statement in the function is "global varname", the subsequent changes to the variable will be visible to other classes.
Here is an example:
# declaring and initializing a global variable
global_var = "I am a global variable."
def func():
??? # accessing and modifying the global variable within the function
??? global global_var
??? global_var = "I have been modified."
# calling the function to modify the global variable
func()
# printing the modified value of the global variable
print(global_var)??? # Output: "I have been modified."

I’m slowly learning the program
I’ve got the part to find the mode working, but have found another problem
I’m using the "TurnoutStatePersistence" script and added a new class for finding the LocoNet Simulator? mode
The script I’m using is set up as several classes.
I can set a variable with the loconet result in its class , but the value won’t show up in the other classes
I have tried using a variable set at the start of the script
This will show up in the different classes, but i can’t change it in one class and it stay changed in the next class
nothing I’ve tried semes to work
Help please
