You will, of course, need ODBC drivers for Sybase SQL Anywhere. When I last
observed someone set up Access and SQL Anywhere (1996, I believe) they were
using third-party ODBC drivers (possibly because they'd used them on other
combinations of Access and server databases with some success). The drivers
used were InterSolv, but I believe the company name has changed.
It's possible that there are ODBC drivers included with Sybase SQL Anywhere.
I'd make it my first order of business to determine if there are.
