GotoStart is an esolang by User:ChuckEsoteric08 and is Turing complete descendant of UBLANG.


GotoStart uses registers (0-indexed) to store data. Language recuires at least 3 registers to be Turing-complete

Instruction Description
+(x) Increment register x.
-(x) Decrement register x if it is bigger than 0.
=(x:y) Set register x to y.
.(x) Output register x.
?(x=y>abc) If registerx is equal to y execute instructions abc.Note that parenthesis should match to make nested if statements possible.
^ Go to the start of the program.

Infinite GotoStart

Programs in this version of GotoStart always end with ^ and ^ is not allowed to appear elsewhere. Despite this, the language still remains Turing-complete.


Repeating Counter

This GotoStart and Infinite GotoStart program counts from one (1) up to inclusive three (3), and perpetually repeats the process, printing each stage to the standard output:



  • Common Lisp implementation of the GotoStart and Infinite GotoStart programming languages.
