The F06 is notoriously difficult to parse. It also can change for different versions of Nastran/ MSC Nastran. Furthermore, the MYSTRAN F06 will have some differences between an MSC Nastran F06. In general, its not a reliable way to parse data (though possible).
Regarding DMAP, I am not sure if MYSTRAN supports it or not (but I think it does not). You can find all known documentation here: https://www.mystran.com/forums/showthread.php?tid=39. Someone else may be able to chime in about this as well.
