# BF instruction extension

Our goal is to extend the instructions of Brainf*ck as far as possible. Anything that you thought of could be one of the instructions. We'll start with the standard commands:

+-><[],.

Then add commands to set the cell to zero, and loops that only loop if the cell is zero:

=()

Then use base-36 to set the cell to that value:

1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ

Then use more base-36 to set the cell to 1 if it's equal to that value, else set to 0:

$§¥€¢£₩«»•abcdefghijklmnopwrstuvwxyz

Then add commands to create pbrain-style procedures:

:{}

Then add commands to load,store,and exchange with the accumulator:

!@*

Then we add commands to do unary bitwise operations (NOT,LEFTSHIFT,RIGHTSHIFT):

~/\

Then we add commands to do binary bitwise operations(stored on the pointed cell) (AND,OR,XOR):

&|^

Now we have this set:

+-><[],.=()1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ$§¥€¢£₩«»•abcdefghijklmnopwrstuvwxyz:{}!@*~/\&|^

## Examples

### Cat program

This infinitely repeating cat program employs the loop-while-zero iteration construct `(…)`

:

=(,.=)

### Truth-machine

This implementation of a truth-machine harnesses the ability to simulate Boolean test results:

,[->+>+<<]>.--------------z[>.<]

## Interpreter

- Common Lisp implementation of the brainfuck instruction extension project.
