SStack

SStack (Seven Stacks) is an esolang by User:ChuckEsoteric08 inspired by Kipple and was designed as more powerful version of Sreg.

Commands

SStack uses seven stacks:a, b, c, d, e, f and g, each containing unsigned integers. If you try to accsess empty stack then it would return 0. Decrementing zero is a nop

>x/y< - pop element from stack x and push it to stack y
+x/y+ - pop element from stack x, increment it and push it to stack y
-x/y- - like +x/y+ but decrement
;x; - push ASCII value of next byte of user input to stack x
:x: - output top of the stack x as ASCII character
"x/y" - push x to stack y
[x\y/code] - execute code while top of the stack x and top of the stack y are equal

Computational class

There is (untested) brainfuck interpreter created in SStack:
