ASA Programming Guode. (Open Client Interface)To run Open Client applications, you must install and configure Open Client components on the machine where the application is running. You may have these components present as part of your installation of other Sybase products or you can optionally install these libraries with Adaptive Server Anywhere, subject to the terms of your license agreement.

Open Client applications do not need any Open Client components on the machine where the database server is running.

To build Open Client applications, you need the development version of Open Client, available from Sybase.

By default, Adaptive Server Anywhere databases are created as case-insensitive, while Adaptive Server Enterprise databases are case sensitive.

For more information on running Open Client applications with Adaptive Server Anywhere, see Adaptive Server Anywhere as an Open Server .

Я его "Открытого клиента" не использую, так что рад бы помочь, но увы

"Открытого клиента" точно поддерживают ASA7.0.4 - ASA9.0.1, думаю что и ASA6 это может, но доки нет.

Java ISQL, Java Central общаются с ASA через JDBC.
Про виндовые версии не скажу.
