What query or command to determine Sybase SQL Anyware version?
I use sqlsh + freetds as interactive client (in Emacs).
For databases, you can use the SYSHISTORY system view to find out what version the database was created at.
select version from SYSHISTORY where object_id = OBJ_ID_OF_DB
If you databases were migrated from earlier installations, and don't show the version number you expect, you probably could just create a small database, and take a look at the version history information.
