Do you have SQL Anywhere 8 installed? If so you can use the SQL Anywhere 8 utility dbisql to run SQL statements.
Do you have a userid and password for the database? If so you can use dbisql to connect to the database and run SELECT and OUTPUT TO FILE statements to extract individual tables to text files.
You can also use the SQL Anywhere 8 dbunload utility to extract all the tables to text files.
You can also use SQL Anywhere 16 dbunload to upgrade the database.
Before discussing these these techniques further, please answer the questions about what you have; in particular, a user id and password... some packaged products only allow database access via their programs, not via direct database connections.
