PATH is an esoteric programming language derived from the Brainfuck language. Programs are arranged on a two-dimensional grid in a manner similar to the language Befunge. Slash and backslash characters are used to direct program flow up, down, left, and right, and "arrow" characters are used to branch program flow. Data is stored in an array of integers called "memory cells", a concept also borrowed from Brainfuck. Among some hackers and hobbyists, an esoteric programming language is a programming language designed as a test of the boundaries of computer programming language design, as a proof of concept, or as joke, and not with the intention of being adopted for real-world programming. ...

Sample code
The following code causes the computer terminal to beep by outputting the ASCII character 0x07 (BEL). There are 95 printable ASCII characters, numbered 32 to 126. ...
/***** /*+* /!*/*! # ! + // * * * /**$**/ * * * * . * +-----+ + +-----+ * * * * * * / / /
Instructions in PATH $ | Start at this position, heading right | # | End program execution | + | Increment the current memory cell by one | - | Decrement the current memory cell by one | } | Change to the next memory cell | { | Change to the previous memory cell | , | Input a character and store the ASCII value in the current memory cell | . | Output the character with the ASCII value in the current memory cell | / | If heading in direction:
right, turn up
down, turn left
left, turn down
up, turn right | | If heading in direction:
right, turn down
down, turn right
left, turn up
up, turn left | ^ | If the value of the current memory cell is not 0, turn up | < | If the value of the current memory cell is not 0, turn left | > | If the value of the current memory cell is not 0, turn right | v | If the value of the current memory cell is not 0, turn down | ! | Skip over the next character | Like in Brainfuck, all characters that are not a valid instruction are skipped over and ignored.
See also SNUSP (for SNUSPs Not Unix, but Structured PATH) is a recast of the Brainfuck programming language into a Befunge-like two-dimensional style, inspired by its predecessor — PATH. Compared to PATH, the SNUSP instruction set stays closer to the Brainfuck language by retaining all instructions related to memory (+, -, > and...
