Hello everybody,
I would like to know if, in ATL, the parameters are passed from a called
rule to another one by reference, or by value.
Thanks

If you pass a model element as argument, then it is "by reference".
Because OCL values are immutable, passing them as arguments can be
considered as being "by value".
