Bobby

Bobby is a small, character-based esoteric programming language based on an accumulator. It has commands for incrementing the accumulator by 2, decrementing it by 1, outputting the accumulator, and printing the string "bobby".

Commands

Command	Description	Python equivalent
b	Increment the accumulator by 2	a += 2
o	Decrement the accumulator by 1	a -= 1
y	Output the accumulator	print(a)
B	Output the string bobby	print("bobby")
O	Output the string bobby	print("bobby")
Y	Output the string bobby	print("bobby")

The language is case-sensitive. All characters except b, o, y, B, O, and Y are treated as comments and ignored.
