Can't find how and where to post bug report. There bug I found in ASE Developer Edition 16:
For example we have table
CREATE TABLE simple_types (
id int PRIMARY KEY,
...
)
Fill it with id from 1 to 5. Open query 'SELECT * FROM simple_types ORDER BY id DESC'. Looks fine. Now open 'SELECT * FROM simple_types ORDER BY id DESC FOR BROWSE'. Result sorted by id in ascending order.
