Scripting sequence of GH Player files

I would like to chain a number of GH Player files together, passing data from one file to the next. I’m trying to do this by writing a Python script, centred around the use of rs.Command("-GrasshopperPlayer FILEPATH) but I’m not sure how to pass inputs into my calls.

I’ve attached two files as an example. The first GH file creates a circle given a point and a radius, and the second extrudes a curve into a cylinder given a height. I want to pass a coordinate into the first file (e.g., [0,0,0] in lieu of a point object), and also pass the circle generated by the first file into the second. How should I do this?
