opcodes

Note:

Every character that does not qualify as an opcode will be loaded into current head's mod field.

Characters that represent digits (between 48 and 57 inclusive) will be loaded into the mod field after subtraction of 0x30 to make operating on numbers possible.

Available opcodes:

  • w: Switches current head to the Write Head.

  • r: Switches current head to the Read Head.

  • <: Moves current head left mod amount of times.

  • >: Moves current head right mod amount of times.

  • /: Moves current head up mod amount of times.

  • \: Moves current head down mod amount of times.

  • y: Moves current head to line mod.

  • x: Moves current head to column mod.

  • .: Writes Write Head's mod the the buffer at Write Head's position, then it increments it's x position.

  • ,: Escapes the next character. Allows for opcodes, as well as chars representing numbers, to be loaded into the mod field.

  • -: Subtracts value of the character after it from current head's mod.

  • +: Adds value of the character after it to current head's mod.

  • =: Adds 0x30 to Write Head's mod, then performs the action of opcode ..

  • ?: Allows for conditional execution.

    If the field before it is not equal to 0 or '0' - it moves the Read Head right by 3 and decrements the checked field.
