LindenMASM

LindenMASM is an Assembly-like esoteric programming language designed by Vioz- of the Code Golf SE site. It allows for the simple writing and displaying of Lindenmayer systems. The current Python implementation of the interpreter does drawing via turtle. It was created for the purposes of a challenge, which was pointed out to be too close to a pre-existing challenge.

Syntax
There are only a few keywords available in LindenMASM.

- Begins every LindenMASM file.

- Sets the axiom (initial state) of the system. - Sets the degree of which all turns will follow, default is 90.
 * $ is a series of commands/variables/constants, ranging from the built-ins plus any user-defined functions.

- Sets the move distance of which all position adjustments will follow, default is 10.

- Sets the number of iterations the generation should go through, default is 0.

- Sets a constant $ to a specified command # - On every iteration, variable/constant $ will be replaced with the command/variable/constant string #. - Ends every LindenMASM file.
 * $ should be a character that is not one of.
 * # will either be a 0 or a 1, where a 0 corresponds to the constant being one that draws forward, and a 1 corresponds to the constant being one that moves forwards.
 * $ should be a character that is not one of . It does not need to be   to be replaced.
 * # is a string of commands/variables/constants that $ should be replaced with.

Each keyword should be placed on a new line. Every file should start with  and end with.

Commands
These are the built-in commands you can use in the axiom, or any replacement.

- Rotates the pointer to the right DEG degrees.

- Rotates the pointer to the left DEG degrees.

- Saves the pointer's coordinates and heading to a list.

- Pops the last value of a list and sets the pointer's coordinates and heading to that.
