1-866-025-4037 is an esoteric programming language made by User:Dragoneater67 in 2026. It is based on combinatory logic.
Overview
The language uses the K', O, Q and R combinators, represented by k, o, q and r respectively, it uses Unlambda-style syntax that uses ` for application. Application is done lazily in left-to-right order. The basis K'OQR is complete as it can express the BCKW combinators as shown on the table.
| Combinator | 1-866-025-4037 expression |
|---|---|
| B | ```rrrq
|
| C | ``rrr
|
| I | `kk
|
| K | ```rrrk
|
| M | `o`kk
|
| W | `q`o`kk
|
I/O
The language has 3 special combinators that are used for I/O:
0-- takes an argument and returns it, has the side effect of outputting 0.1-- takes an argument and returns it, has the side effect of outputting 1.?-- takes 2 arguments, inputs a bit from the user, and if it is equal to 1, return the first argument, else, return the second argument, returns neither on EOF.
Examples
