Finite looping automaton is a misleading, or outright incorrectly named esoteric programming language attempt invented by User:A where some programs, demonstrated by the examples below, can loop infinitely. It could theoretically simulate only loops with predicted numbers of iterations (e.g., for loops), but using self-modification, it can simulate infinite loops.
Syntax
n ... ]
: loop...
n times, with n decremented after each looping process. Executing 0 times is a comment.>
: Move the program pointer (not the program counter, its motion depends on the program) right.<
: Move the program pointer left.+
: Increment the instruction's ASCII code pointed by the program pointer.-
: Decrement the instruction's ASCII code pointed by the program counter.*
: Halts the program.- Any other command puts that ASCII code into the program.
The whole program gets outputted on the end of the execution.
Example programs
Infinite loop
9+] -
Looping counter
This evaluates only 1 iteration. The user should execute the outputted program repeatedly.
0+
This loops forever:
90+>+<]
Downward counter from 9 to 0
This is used as a counter-argument. It is usable for computation...
