The title of this article is not correct because of technical limitations. The correct title is actually INF>xO.

INF>xO is an esoteric programming language made by User:AmNow. INF>xO was made so that you can have infinite output without loops.


Version 1.3

€([a]’[b]… )

defines a N-dimensional vector. e.g.: €(z’34’|’)

note: INF>xO uses base 37 ([0-9][a-z]Æ, | (pipe) references infinity)

To declare/set a variable, use:


To reference the value in one, use:


To get a single value from a vector (note: zero-indexed):

+,-,* and / do math: e.g.: 2+2

+ can be used for concatenation of vectors: e.g.: €1’2+€3’4 results in €1’2’3’4.

* can be used for multiplication of vectors e.g.: €35*| results in €35’35’35…

p;[object]; Output as Unicode.
P;[object]; Output as base 37.
R;[object]; Output as base 10.
i Input a vector in Unicode.
I Input vector in base 37
Ī Input vector in base 10
j Input Unicode character and use the ID.
J Input number in base 37
~ Input number in base 10
¥[cnd]«[code]» while cnd returns true, do code.
;[cnd]^[true-code]«[false-code] if cnd is true, do the true code, else do the false code, [false-code] is optional.
\ End program.
