Iwashi

Iwashi, crated and published by Yosshi999 in 2018, is a procedural language whose commands are taken from lyrics from the song A sardine grows from the soil. It's a brainfuck-derivative except:

1. it lacks commands to increment/decremented the pointer; instead it has a command to move the pointer to specified position: as in (\d+)ねんまえかのことでした where it is capable of pointer 0-2018;
2. the loop commands are substituted by label and branch commands: (.+)にあながあく, (.+)がつちからはえてくるんだ and そらのうえから(.+)がたつ for label, branch if positive, branch if zero respectively; and
3. it has integer I/O and arithmetic commands.

For character input, EOF is represented as -1.
