Nemo aed6f0a372 [08] Finishes VM Implementation 
Lots of different changes:

- modular code with lots of helper methods
- fixed the return jump address getting overridden bug
 2020-06-08 23:56:54 +05:30
Nemo 979976cb93 [docs] Fix chapter numbers 2020-06-04 15:48:52 +05:30
Nemo 286df5b147 [08] Finishes call/init implementation 
Found 2 bugs:

0. ic+=10 is incorrect jump for the boolean compare methods
1. Another bug was in the write() method, which was increasing the instruction
counter even for label commands, which aren't supposed to do that.

Another minor issue in my interpretation of the "call" to `Sys.init`
which I was so far just doing via a jump. Changed that to a proper call
