In explicit status checking, shown at 9 in Title not available,
you explicitly examine an SQLCA field for a particular value, then
perform an operation if the value exists.
In this
example, the SQLCA field named SQLCODE is examined
to determine whether it contains a value less than -14024. SQLCODE
values with greater negative values than -14024 indicate errors serious
enough to warrant terminating the program. If SQLCODE is less than
-14024 in this case, the ABORT-FLAG is set and the program is
terminated after paragraph S200-SQL-EXPLAIN is executed.
