This variable enables the Oracle Hints feature. The default value is 1 (on, true, yes). To turn off this feature, set it to 0 (off, false, no).
Oracle Hints can improve database performance considerably in some situations, by "strongly suggesting" to the Oracle query optimizer that it use a given index to process a query.
Note that keys must use your COBOL development system's naming convention for naming indexes in the database to use this function. For example, the primary key on the file ftest would be named "iftest_0".
