How do I pass a tuneable parameter to the exe as a command line argument

I have generated an executable from my simulink model, which is designed to run on the windows platform. I have a batch file that I use to start the application.

What I would like to do is pass a variable on the command line (from the batch file) to configure a parameter used in the model. Is this possible, and if so how.

Thanks in advance for any help.

To which block do you need to pass the parameter?

Hi pietro, I currently have the parameter defined in the workspace as a Simulink.Parameter which is used in a constant block (it is a multiplier in the model). What I would like to do is alter this parameter without having to rebuild the application.
