Blue Hens

Blue Hens is an interpreted programming language by User:ProfNinja designed for a CTF competition, inspired by Chicken.
==Language Overview==
Your input is a text file.
Each line may have the word "blue" some number of times followed by the word "hens" some number of times, space-separated.
The number of "blues" on the line is the OPCODE the number of "hens" on that line is the ARG.
The line numbers matter and they start at 1.
Our architecture has 2 variables, a register REG and a counter CTR both start at 0.
OPCODES 1,2,3,4 are arithmetic operations
OPCODES 5,6,7 are gotos
OPCODES 8,9,10 are control flow:
OPCODE 11 is print
==The OPCODEs==
There are 11 opcodes:
OPCODE
