Pancake Stack
This page is a work in progress
Pancake Stack is a stackbased esoteric programming language created by User:JWinslow23 in 2013, in which programs require you to manipulate a stack of pancakes.
Syntax
The pancake stack starts out as empty.
Code  Meaning 

Put this X pancake on top! 
Push the word length of X on top of the stack, i.e. "wonderful" would push 9. 
Eat the pancake on top! 
Pop the top value off of the stack, and discard it. 
Put the top pancakes together! 
Pop off the top two values, add them, and push the result. 
Give me a pancake! 
Input a number value and push it on the stack. 
How about a hotcake? 
Input an ASCII character and push its value on the stack. 
Show me a pancake! 
Output the top value on the stack as an ASCII character, but don't pop it. 
Take from the top pancakes! 
Pop off the top two values, subtract the second one from the first one, and push the result. 
Flip the pancakes on top! 
Pop off the top two values, swap them, and push them back. 
Put another pancake on top! 
Pop off the top value and push it twice. 
[label] 
Defines a label to go back to (Can also define a comment, if needed). When you go back to the label, it goes to the line number (1 indexed) of the top value of the stack when the label was defined. 
If the pancake isn't tasty, go over to "label". 
Go to label [label] if the top value is 0.

If the pancake is tasty, go over to "label". 
Same as above, except go if the top value is not 0. 
Put syrup on the pancakes! 
Increment all stack values. 
Put butter on the pancakes! 
Increment only the top stack value. 
Take off the syrup! 
Decrement all stack values. 
Take off the butter! 
Decrement only the top stack value. 
Eat all of the pancakes! 
Terminate the program.

Cat program
Put this old pancake on top! [CAT] Eat the pancake on top! Give me a pancake! Show me a pancake! If the pancake is tasty, go over to "CAT". Eat all of the pancakes!
This is for numeric input. For ASCII input, replace "Give me a pancake!" with "How about a hotcake?"
Computational class
Pancake Stack is Turing complete assuming stack values are unbounded, as it can easily simulate a tworegister Minsky machine using the top two stack values as registers.
Alternatively, if stack values are bounded, then Pancake Stack is not Turing complete, as it can be simulated by a pushdown automaton. Some trick is needed to support incrementing/decrementing all values simultaneously, e.g. one could keep track of a separate value (in the automaton state) to be implicitly added to all stack values.
