The Schizophreniac From Muhosransk

The Schizophreniac From Muhosransk is an esoteric programming language made by User:Dragoneater67 in 2026.

Overview

The program is a set of instructions executed in random order in an implicit infinite loop. There is an infinite 1-indexed array of unbounded nonnegative integer registers initially set to 0.

The Schizophreniac From Muhosransk instruction table

Instruction	Description
+x	Increment register x.
-x	Decrement register x if register x is not 0.
?x { code }	Execute code (in random order) if register x is 0.

I/O extension

These commands add support for I/O.

I/O extension instruction table

Instruction	Description
>x	Output register x's value mod 256 as an ASCII character.
<x	Input a character and store its ASCII code in register x.

Computational class

The Schizophreniac From Muhosransk is equivalent to this 2-register Minsky machine:

• INCA increment register A.
• DECA decrement register A.
• JZA x if register A is equal to 0, jump to line x.
• INCB increment register B.
• DECB decrement register B.
• JZB x if register B is equal to 0, jump to line x.
• JMP x jump to line x.

Lines are 1-indexed.

Each program starts with:

?1 { +1 -2 -5

Then for each line except line 1:

 ?n { +n }

Here, n is equal to line number + 4. Then add:

 }

Then each line is converted using this table:

MM	TSFM
INCA	?n { ?2 { +3 +n -m } ?1 { ?2 { +2 } -3 } Then for each line: ?n { +n } Then add: } Here, n is line number + 4 and m is n + 1.
DECA	?n { ?2 { -3 +n -m } ?1 { ?2 { +2 } } Then for each line: ?n { +n } Then add: } Here, n is line number + 4 and m is n + 1.
JZA x	?n { ?2 { ?3 { +n -y } ?n { +n -m } } ?1 { ?2 { +2 } } Then for each line: ?n { +n } Then add: } Here, n is line number + 4 and m is n + 1 and y is x + 4.
INCB	?n { ?2 { +4 +n -m } ?1 { ?2 { +2 } -4 } Then for each line: ?n { +n } Then add: } Here, n is line number + 4 and m is n + 1.
DECB	?n { ?2 { -4 +n -m } ?1 { ?2 { +2 } } Then for each line: ?n { +n } Then add: } Here, n is line number + 4 and m is n + 1.
JZB x	?n { ?2 { ?4 { +n -y } ?n { +n -m } } ?1 { ?2 { +2 } } Then for each line: ?n { +n } Then add: } Here, n is line number + 4, m is n + 1 and y is x + 4.
JMP x	?n { ?2 { +n -y } ?1 { ?2 { +2 } } Then for each line: ?n { +n } Then add: } Here, n is line number + 4, m is n + 1 and y is x + 4.
