Referral Substructure
A referral substructure redefinition associates a new referral substructure with a
previous item at the same BEGIN-END level of a structure.
identifier
is the identifier of the new substructure.
referral
is the identifier of a structure that provides the structure layout. You can specify any
previously declared structure (except the encompassing structure) or structure
pointer. If the previous structure has an odd-byte size, the compiler rounds the size
of the new substructure up so it has an even-byte size.
