DBFV! is an esoteric programming language by User:David.werecat where each line of code is a separate function.
Instructions
Instruction  Description 

x:[] 
Defines a loop for x not zero 
x:() 
Defines a loop for x is zero 
x<n 
Sets x to equal n 
x> 
Outputs the ascii value of x 
!n 
Jumps to function n 
~n 
Calls function n 
^ 
Returns from a call 
x+ 
Increments x 
x 
Decrements x 
>x 
Reads a value and stores in x 
x% 
Skips the next instruction if x not zero 
x& 
Skips the next instruction if x is zero 
+n 
Skips n characters ahead in the line 
xn 
Swaps the values in x and n 
.x 
Sets x to zero 
*xn 
Adds n to x 
$n 
Ends the program and returns n 
n/ 
Pushes n into stack 1 
/x 
Pops stack 1 and puts in x 
n\ 
Pushes n into stack 2 
\x 
Pops stack 2 and puts in x 
@text@ 
Defines a comment 
In the examples, x
and n
are registers. Registers are defined as A
Z
(uppercase) and store a single wrapping byte of data. n
can also be an immediate constant, which is a number from 09.
Whenever the instruction to be skipped is a loop, the entire loop is skipped.
Computational class
The following translation rules from Brainfuck show that DBFV! is Turingcomplete.
