;;;
;;; is an esolang made by User:Yayimhere.
memory
memory is stored in a infinite tape holding 8 bit numbers.
syntax
these are the commands:
| symbol | command |
|---|---|
; |
if current cell is 0 go left on tape. else decrement it |
: |
increment current cell and go right. however if this increments 256 go left and goto the line equal to the current cell |
/ |
decrement current cell. if this decrements 0 however jump back to the start of the program |
\ |
go left unless current cell is a prime number |
Examples
Conditional Cell Pointer Translation
The following code generates the first two prime numbers two (2) and three (3) in the first two memory cells, translates the cell pointer one step to the left, preventing a second translation via the prime number check, and increments the second cell value from three (3) to four (4):
:;::;:;:;\:
Infinite Sequence of Ones
This example generates an infinite sequence of one-valued cells by adminiculum of the program restart mechanism:
:/
Counter
The program perpetually increments the leftmost cell from inclusive zero (0) to inclusive 255 and subsequently prepends a further counter with a zero-valued interstitial cells betwixt the new and the previous counting cell, doing so while employing the conditional goto facility:
\ :;:;:;:;:;:;:;:;:;:;:;:;:;:;:;: /
Interpreter
