THIS thread. It provides instructions to create an ODBC data source with the Client/Server Pervasive.
There my be some minor differences between it and your version 8.5, but they should be minor.
The basic process to create an ODBC data source is:
1. Run ODBCDDF from DBA. (in Classic, use UT-A, and enter ODBCDDF as the program to run)
2. Create an Engine ODBC data source on the server that points to the newly created DDF files
3. Create a Client ODBC data source on the Client Machine that points to the Engine data source created above
I hope this helps.
