Set the supplied atom with the value of the supplied member. Note that for BINARY/TXTDOC members, the atom is set with the binary datum id, not the binary datum value.

Function body:

   //  Set the supplied atom with the value of the supplied member. Note that for BINARY/TXTDOC members, the atom is set with the binary datum id, not the binary datum value.
   //  
   //  Arguments: 1) atom The atom to be set
   //     2) pMbr Pointer to the data class member
   //     3) nOset Default 0, applicable only if the member is an array
   //  
   //  Returns: E_NOINIT If the object has not been initialized to a class
   //     E_CORRUPT If the supplied member number does not identify an object class member.
   //     E_TYPE  If the object class member is not atomic (is another class) or if the supplied atom has the wrong type.
   //     E_RANGE  If the requested element (nOset) exceeds the number of member values
   //     E_OK  If the object class member has been set to the supplied atom value.
