As you may or may not know, ive always been interested in languages/compilers/interprets so I did my weekly x hour codeathon (this weekend it was 2 hours)...and StackFck2d was born!

Its just like Brainfck but with 6 new commands...here is the complete listing of commands:


>	moves the pointer east.
<	moves the pointer west.
^	moves the pointer north.
v	moves the pointer south.
+	increment (increase by one) the value(top of the stack) at the pointer.
-	decrement (decrease by one) the value(top of the stack) at the pointer.
.	output the value of the byte(top of the stack) at the pointer.
,	accept one byte of input, storing its value in the top of the stack at the pointer.
[	jump forward to the command after the corresponding ] if the byte at the pointer is zero.
]	jump back to the command after the corresponding [ if the byte at the pointer is nonzero.
@	pushes an empty cell onto the top of the location's stack
#	pops the top most cell off of the location's stack
%	copies the current location's value and places it into the global variable
&	pastes the global variable's value into the current location's value

Now, let me explain the new aspects. Its not 1d like BF, this is 2d. You can move in 4 directions instead of 2. Also, each "cell" is now a stack. When you use + and -, you affect the top of the stack. There are also 2 commands for coping and pasting cells.

I did this in 2 hours so the code is ugly, crammed into 2 functions, and may not work 100%! The loops is the only aspect that may not work perfectly, but from my few tests, they worked. Here is the compiler with source:

I know its not much and doesnt add much greatness to BF, but I wanted a project to mess around with in a short amount of time and learn some things about the STL. Have fun
