TwoFiftyFive

TwoFiftyFive is an esoteric programming language by User:HereToAnnoy with only two instructions and limited memory.

Instructions

 * Move instruction : Sets RAM to . Whitespace is allowed after a move instruction.
 * Pointer instruction : Gets RAM. This is stackable and can be used as the input of a move instruction.

Memory mapping
There are 256 bytes of RAM in TwoFiftyFive. In order to do computation, some indexes of RAM are memory mapped.

Memory Extension
In order to actually get anything done, TwoFiftyFive will probably need more memory. In order to achieve this, we can combine multiple programs into one, which can communicate using the stack. Here's an example that forever outputs the value 1: :             //Header for a program called "Generate" FB01  FF00      //"" tells the interpreter to switch execution to program "Output". This is NOT an instruction, and can not be jumped to. : FA*FB  FF00 Each program in the above example has its own memory and instruction pointer. When a program is swapped to, it's instruction pointer will resume to the location it ended in the previous time executing the program (defaults to 0). A program without any headers is just counted as a single program.

Hello, World!
FA48 FA65 FA6C FA6C FA6F FA2C FA20 FA57 FA6F FA72 FA6C FA64 FA21 FF0D Output: 48 65 6C 6C 6F 2C 20 57 6F 72 6C 64 21 (Hex) Hello, World! (UTF8)

Computational class
TwoFiftyFive is probably possibly turing complete using the memory extension.
