SE.STRUCT(SEMemberDesc)
You can use this macro to retrieve the member from an SEMemberDesc object and pass it to any of the functions. You store a member in the Object using the seStoreMember function. Here is a short code example:
SEMemberDesc mem = new SEMemberDesc();
se.seStoreMember(mem,SE.NUM(0));
se.sePutNumber(myObj,SE.STRUCT(mem), 10);
Member description structures are useful to pass a member identifier as a parameter to a function.
