Thx first.

Actually, i hv a dos software that can do some data maintenace , and the software only support foxpro 2.0 database, and if i want all of the database work together well, i need to change my vfp program 's database into foxpro 2.0 type.
But i found that if i use the dos software to open my vfp datbase (which are already changed into database type foxpro 2.0) and also open with the CDX index file, a error occurs. so i want to know whether the CDX need to change into foxpro 2.0 database supported or not!
