I am not registered on Esolang Wiki. Also, I cannot register on Esolang Wiki, because the CAPTCHAs are too hard.

Deadfsh is an esoteric programming language like Deadfish, but this one doesn't have the increment command. It doesn't follow the "acc == -1 || acc == 256" tradition.

Commands

d: Decrement
s: Square
o: Output

JS Interpreter

var input = "dso";
var number = 0;
for (var i = 0; i < input.length; i++) {
 if (input[i] == "d") {
  number -= 1;
 }
 if (input[i] == "s") {
  number *= number;
 }
 if (input[i] == "o") {
  console.log(number);
 }
}

Examples

XKCD Random Number

ddso

Extensions
