Brainstuck

Brainstuck is a variation of Brainfuck, with a stack instead of a tape.

Commands

The commands are:

Token	Command
`+`	Increments the top value of the stack.
`-`	Decrements the top value of the stack.
`.`	Pops the top value of the stack, and outputs it.
`,`	Pushes a byte from stdin on the stack.
`0`	Pushes 0 onto the stack.
`:`	Pops the top value of the stack, and pushes the value at a depth of that depth into the stack onto the stack.
`[`	Pops the top value of the stack, and if that value is 0, jumps to the opcode after the corresponding `]`.
`]`	Jumps to the corresponding `[`.

0+[,0:.+]

It is possible to convert into Forth codes by:

+  1+ 255 AND
-  1- 255 AND
0  0
:  PICK
,  KEY
.  EMIT
[  BEGIN WHILE
]  REPEAT

Some other commands in Forth can be also using the Brainstuck codes:

DUP              0:
OVER             0+:
THEN             0]
0 *              0:[-0:]
DROP             [0:[-0:]]
