DOG
DOG is an esoteric programming language created by Jeremy Ruten. The commands in this program are supposed to look like commands you'd give to a dog. Numbers are represented as piles of cookies. Piles of cookies (numbers) are stored in dishes, plates, and the floor. Dishes are named dish0, dish1, ..., dish9. Plates are named plate0, plate1, ..., plate9. So you only have 10 dishes and 10 plates. The floor should hold as many numbers as you want. When you get a number from the floor, the dog (the interpreter) will choose a random number from the floor that isn't 0. Negative numbers are allowed.
Each command must be seperated by a newline. Any command can be preceded with a number or variable (dishx, platex, or floor). This number or variable tells the dog how many times to execute that command. This is where the difference between dishes and plates comes in. If a dish variable precedes a command, the command is executed however many cookies is in that dish. But if a plate variable precedes a command, the command is only executed once if the number of cookies on the plate is not 0. If the number of cookies on the plate is 0, the command isn't executed at all. This is useful for making the equivalent of a "jump if not zero" command.
Comments start with 0 (which means "execute this command 0 times") and end at the next newline. If you try to do a command a negative number of times, the command won't be executed at all.

Command list
Where X appears, you can replace it with dishX, plateX, floor, or a number. Where V appears, you can replace it with dishX, plateX, or floor, but NOT a number. If X or V appears in square brackets, it's optional.
- fetch X - Place X cookies into dog's mouth, adding onto whatever number is already there.
- drop V - Move cookies from dog's mouth into V, adding onto whatever number is already there.
- pickup V - Move cookies from V to dog's mouth, adding onto whatever number is already there.
- eat [X] - Subtract X amount of cookies from dog's mouth. If X isn't provided, dog eats all cookies.
- clear V - Resets V to 0. If V is floor, it resets the entire floor to 0.
- die - Ends the program. Dog dies. :(
- take - Waits for user to input a number and adds that number to the dog's mouth.
- show - Prints the number that is in the dog's mouth.
- give - Prints the number that is in the dog's mouth and resets dog's mouth to 0.
- bark "string" - Prints whatever is in the quotes to the screen. Use \n to print a newline.
- jump label_name - Jumps to the label label_name.
- label label_name - Where a jump command jumps to when jumping to the label "label_name".

" 0 Get the answer, store it in dish3 fetch dish1 fetch dish2 drop dish3 0 Take user's guess take 0 Check if it's right by subtracting the real answer from their guess and checking if the result is 0 eat dish3 drop plate1 plate1 bark "Wrong!" plate1 die bark "Right!"
