lower-bound

is an INT constant expression (in the range -32,768 through 32,767) that

specifies the index (relative to the zeroth structure occurrence) of the first

structure occurrence you want to allocate. Each occurrence is one copy of the

structure.

specifies the index (relative to the zeroth structure occurrence) of the last

structure occurrence you want to allocate. For a single-occurrence structure,

omit both bounds or specify the same value for both bounds.
