Thanks for the clarification! Now,
As i read the file opcodes.txt (that came with 0.8.2 tarball) in the VVP directory, i get to understand that there are two types of registers the index register(0-3) that are used with "ix" instruction set and the bit wise registers. So, two questions here. 1. How many bit wise registers are present? 2. What is the length of the index registers? please correct me if i'm wrong in understanding this.
