No. Constants are replaced in the model with their value during compilation.
You have to make it a parameter. And even so, if is a structural parameter it might not be possible to change.

thank you Adrian for the quick reply.
Is there a workaround in order to change a parameter value using the init file values?
My idea is to place a capacitor without discharge and set the initial voltage.
The model reads the voltage. If it is under a threshold the state is "false", if it is over the threshold the state is "true"
I need "only" to change a state from 0 to 1 in order to switch on/off part of my model

Well, if making it a parameter (with fixed=false) instead of a constant doesn't help then the
only way I can think of is to make 2 executables, one with the constant set to true and one
with it set to false and call them with -override for the other values.

Thank you Adrian!
Your solution is effective and easier than mine.
I'll try it!
