Being experienced in Lite-C helps a lot, so it shouldn't be that hard to write your first Zorro script. Zorro supports Lite-C and C++, see https://zorro-project.com/manual/en/started.htm Lite-C is pretty much the same as C.

The workshops in the manual, see https://zorro-project.com/manual/en/tutorial_var.htm for the first one, are a good starting point.
