Magic number starts the file "IEX" or 0x49 0x45 0x58

The header of the file can be represented as such

;struct IEX_HEAD {
    raw {3}char     # Always "IEX"
        magic,
        
    {}char
        name,
        arch,
        os,
    
    uint8           # Version info
        major,
        minor,
        patch,
                    # OS abi info
        os_major,
        os_minor,
        os_patch,
    
    bool            # Tells loader that the file holds a main function
        can_execute,

    ~void ({}{}char args) [int]
                    # Address of main in file
        start_addr,

    {}IEX_SECTION
        sections,

    {}IEX_LIB
        dependencies,
    
    IEX_MODULE
        self
}

a section is defined as

;struct IEX_SECTION {
    {}char
        name,
    
    uint8       # Denotes dependency, symbol table, data, bss, text, etc.
        type,

    ~void       # Points to start and end of section
        start,
        end
}

;struct IEX_LIB {
    {}char
        name,
    
    uint8       # Version info
        major,
        minor,
        patch
}

;struct IEX_MODULE {
    {}char
        name,
    
    {}IEX_FUNCTION
        func,
    
    {}IEX_TYPE
        types,

    {}IEX_MODULE
        sub
}

;struct IEX_FUNCTION {

        overload,
        bytes_in,
        bytes_out,
    
    ~void
        addr
