Oxon

Oxon is an esoteric programming language. Programs written in it have to use the source code for memory, making Oxon Self-modifying.

When a program is run, a copy is made of that program, which is what is executed. The original program stays unchanged.

Data types

Data type	How to write
Integer	( )
String	" "
String at program line	* *

There are 3 different ways of representing information in Oxon:

• (x) - interprets x as an integer
• "x" - interprets x as a string
• *x* - Interprets the contents of line x of the program as a number, if only containing numerical characters, else interpret as a string

Commands

In Oxon, every program line begins with a command, followed occasionally by reporters and arguments. The commands available are:

Command	What it does
P	Prints argument A on a new line. If A is a number, print the ASCII character corresponding to that number.
W	Writes argument A to program line B.
F	If argument A is equal to argument B, go to program line C.
E	Stops program.

Reporters

Likewise, these are the reporters available:

Reporter	What it does
A	Takes arguments A and B. if they are both numbers, add them. If they are both strings, join them.
S	Takes arguments A and B. if they are both numbers, subtract them.
I	Takes user input. No arguments.

Comments

Comments are represented by text inside square brackets - [text]
