Max gen: how to save "param" parameters?

Hey! I am new to this and tried to build my first effect using Max Gen.

I managed to save and compile it but I realized that none of my parameters (floats) from the Max Patcher, that I sent to the Max Gen using “param”, were saved inside the compiled h and cpp files.

I am trying to save parameters for filter coefficients for a BiQuad Filter.

How can I do that?

I hope you understand my question. :wink:

Thanks in advance for your help.
Cheers
