4.2.3 Defining a binary item ⎧15⎫
[level-number ]item-name TYPE IS FIXED REAL BINARY[ ⎨ ⎬].

Binary items can contain integers only. They are used exclusively as computational items
by the database programmer and cannot be printed without pr ior editing by a DML program.
Binary items require less storage space and ca n be processed faster than packed or
unpacked items.
If BINARY 15 items are not aligned to halfwords and BINARY 31 items are not aligned to
words by the user, UDS/SQL aligns them automatically.
level-number denotes whether the item is part of a repeating group:
If the item is not to be part of a repeating group, the specified l evel number should be the
smallest level number in the whole record type.
This is especially important if the item is to be used as a key item.
If the item is to be part of a repeating group, proceed as descr ibed on page 66.
item-name specifies the name assigned by the user.
BINARY 15 is used to define a binary item with a value range of -215 through 215-1.
BINARY 31 is used to define a binary item with a value range of -231 through 231-1.
If you do not specify a number, the default value BINARY 15 is assumed.
