Describe the issue in detail and how to reproduce it:

When using Variable Control, performing RANDOM operations with variables rather than constants does not behave as expected, and seems to be ignoring the variable designation entirely, treating it as though it were a constant.

The attached WEBM is a step-by-step walkthrough of a CBS damage formula that uses this, demonstrating the sharp difference between the RPG_RT handling, and the EasyRPG Player handling of the variable control.

This appears to be bitfield stuff again:

Lower bits of Parameter 7 is for the 1st arg, upper bits (4 bit groups) is for 2nd arg
