This human readable format is parsed by the assembler which will output the actual binary opcodes and operands.
## Flags
Some instructions will change certain flags based on their result. These are in a special non read-write register.
The only way to set these flags is by using instructions and the only way to read these flags is with the jump behavior.
> NOTE: The flags might be readable in the future
Some instructions will change certain flags based on their result. These are in a special non read-write register. These flags are used for the family of jump instructions. You can also use the [`PUSHF`](#pushf) and [`POPF`](#popf) instructions to query and manipulate the flags
