A_ORA_NLS_SORT configuration variable

This variable forces the sort order of returned records to be in a binary order. Set A_ORA_NLS_SORT to 1 to turn off the default binary order and use the native language sort (NLS) instead. The default is 0, which means that the sort order is not NLS order and will be binary.

This variable must be set before the first database file is accessed.
