1234567890
1234567890 is an esolang by User:Yoyolin0409 ,It is a very simple programming language used to convert content into other "number" languages at any time.
Furthermore, it is not yet implemented.
This programming language is Turing-complete because at least one of the numerical languages it uses is Turing-complete.

Instruction list
| Instruction | Use |
|---|---|
| ---START <num>--- | Change to another language |
| ---END--- | Stop change to another language |
| ---START 1234567890--- | Equivalent to ---END--- |
| ---ABCDE--- | Enable abcde expansion |
Regarding <num>, all programs listed in "Influenced by" are available. The following programming languages can only be converted when the abcde extension is enabled:A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R++(Replace with "R"),S*bleq(Replace with "S"),T,U,V,W,X,Y,Z,!,@,#,$,%^2^-1(Replace with "%"),^,&,*,(,)
Example
Hello World!
---START 01--- hello=0100100001100101011011000110110001101111001000000 1110111011011110111001001101100011001000010000100001010. ---END---
Cat and Quine
---START 0--- 0 ---END---
Notes
You might wonder why 6ix can be considered a number. In fact, it's a combination of algebra and imaginary numbers. Furthermore, we only accept x as an algebraic number, so don't ask me why there's no "3D".
