<div><p>Any level 77 data description entry can be followed by one or more

REDEFINES entries. However, the names in these entries cannot be used in SQL

<div class="section"><p>Unpredictable results may occur when a structure contains levels

defined below a FILLER item.</p>
|
|
<p>The COBOL declarations for SMALLINT, INTEGER,
|
|
and BIGINT data types are expressed as a number of decimal digits. The database
|
|
manager uses the full size of the integers and can place larger values in
|
|
the host variable than would be allowed in the specified number of digits
|
|
in the COBOL declaration. However, this can cause data truncation or size
|
|
errors when COBOL statements are being run. Ensure that the size of numbers
|
|
in your application is within the declared number of digits.</p>
