MicroBasic and openCAN

I'm using the SBL2360T controller. In the CANBus Networking Manual, openCAN section, it mentions the commands "run MicroBasic script" and "Set User Integer Variables".
I cannot find any information anywhere how this works.
1. How do I select in the CAN command "run MicroBasic script" which script to run? Is it byte0 of the command?
2. Is the "Set User Integer Variables" command for the MicroBasic script in question? How does this work exactly? Are there examples of this somewehere?
3. What is the max number of scripts that I can have in the controller flash?

Thanks!
