Call the Grasshopper

Guys,

I need to control some parameters in Grasshopper from an external tool, so I need to know how to make a batch file for the grasshopper? Does anyone know?

I do really have problem in my research. Any help would be appreciated a lot.

Thanks,

grasshopper is a very good platform to call the other apps ,and gh can edit and run batch file , so I wonder in which platform/tools you wanna call grasshopper.
