I have not looked at the kargc family of opcodes so I cannot answer
the question about compatability.  I still think that global
parameters are a better way of passing data between opcodes, but I
expect i will be overruled.
  My schedule opcode is very similar to your icall except that I was
writing it before I heard about icall.  The code I ended up with did
borrow from your code.  

BTW, in your icall there is an error related to the carry flag, as it
is static/local to the file in your code, but it needs to be global.
