Blue Hens

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

OPCODE	MNEMONIC	ARG?	DESCRIPTION OF CODE
1	SET	Y	Set REG to ARG
2	ADD	Y	Add ARG to REG
3	SUB	Y	Sub ARG from REG
4	MUL	Y	Multiply REG by ARG
5	GTL	Y	Goto line ARG
6	GBL	Y	Go back ARG lines
7	GUL	Y	Go up ARG lines
8	CTA	Y	Add ARG to CTR
9	CTS	Y	Sub ARG from CTR
10	SKP	N	If CTR 0 skip next line
11	PRT	N	Print REG (ascii)
