SideStacks is a Stack-Based programming language made by User:Myoitzi housing two stacks and two 8-bit registers.

Instruction set

SideStacks uses a multitude of Single-character instructions, similar to brainfuck. A list of instructions is provided below:

Command Description
^ Increment the "A" register.
v Decrement the "A" register.
> Push the value of the "A" register to the selected stack and set "A" to 0.
< Pop the topmost value of the selected stack to "A".
+ Pop the topmost value of the first stack and add it to "A".
- Pop the topmost value of the first stack and subtract it from "A".
s Swap the values of the "A" register with the "B" register and vice versa.
b Duplicate the value of the "A" register and store it into the "B" register.
. Print the "A" register as a decimal number.
@ Print the "A" register as an ASCII character.
; Take an integer input and store it into "A".
: Take an ASCII input and store it's corresponding value into "A".
0 Set "A" to 0.
( Jump past corresponding parentheses if "A" is 0 (similar to [ in brainfuck).
) Jump back to the corresponding parentheses if "A" is nonzero (similar to ] in brainfuck).
[ Jump past corresponding parentheses if the "A" is nonzero.
] Jump back to the corresponding parentheses if "A" is 0.
{ Jump past corresponding parentheses if the "A" is equal to "B".
} Jump back to the corresponding parentheses if "A" is not equal to "B".

Any character not in this table will be ignored

Examples

Hello World!:

^^^^b<s+b<s+b<sb<sb<s+++^^^^^^^^@b<s<^^^b<s+^b<s+b<s+^+@^^^^^^^@
@^^^@0^^^^b<s+b<s+b<s+@0^^^^b<s+b<s+v+@<^^^^b<s+b<sb<s+++@^^^@vv
vvvv@vvvvvvvv@0^^^^b<s+b<s+b<s+^@
