whereas:
type =0 start =1 select =2 set =3 stop flgs1 bit 0 called from 32 bit code bit 1-6 seamless session bits ? bit 7 VDM start session bit 8 ? flgs2 =0 terminate child =1 terminate all children param variable length field to store different parameters depending on DosStart/Stop/Set/SelectSession
