Customer.SetRemoteAccess(True) // The following HFSQL commands will be performed remotely
Customer.Open() // Open a remote file
//...
Orders.SetRemoteAccess(False) // The Orders data file becomes local
Customer.ReadFirst() // Read the first record remotely
Orders.ReadFirst() // Read the first record locally
