Repair corrupt sqlanywhere 9 database with no backup. Assertion failed: 201129 (9.0.2.2451) File is shorter than expected.

I am looking for help in attempting to repair a corrupt SQL Anyhere 9 (9.0.2.2451) database. There is no backup of the database. The database service will not start and gives the following error: Assertion failed: 201129 (9.0.2.2451) File is shorter than expected. Is repairing the database possible? Could data from the database be salvaged to use in creating a new database? I have tried unloading tables using the dbunload command but the same 201129 error occurs when I make the attempt.
